History of Statistic
By the 18th century, the term "statistics" designated the systematic collectionof demographic and economic data by states. In the early 19th century, themeaning of "statistics" broadened, then including the discipline concernedwith the collection, summary, and analysis of data. Today statistics is widelyemployed in government, business, and all the sciences. Electronic computershave expedited statistical computation, and have allowed statisticians todevelop "computer-intensive" methods. The term "mathematical statistics"designates the mathematical theories of probability and statistical inference,which are used in statistical practice. The relation between statistics and
probability theory developed rather late, however. In the 19th century,statistics increasingly used probability theory, whose initial results werefound in the17th and18th centuries, particularly in the analysis of games ofchance(gambling). By 1800,astronomy used probability models and statisticaltheories, particularly the method of least squares, which was invented byLegendre and Gauss Early probability theory and statistics was systematizedand extended by Laplace; following Laplace, probability and statistics havebeen in continual development. In the19th century, social scientists usedstatistical reasoning and probability models to advance the new sciences ofexperimental psychology and sociology; physical scientists used statisticalreasoning and probability models to advance the new sciences ofthermodynamics and statistical mechanics. The development of statistic wasclosely associated with the development of inductive logic and the scientificmethod Statistics is not a field of mathematics but an autonomousmathematical science, like computer science or operations research. Unlikemathematics, statistics had its origins in public administration and maintainsa special concern with demography and economics. Being concerned with thescientific method and inductive logic, statistical theory has close associationwith the philosophy of science; with its emphasis on learning from data and
making best predictions, statistics has great overlap with the decision scienceand microeconomics. With its concerns with data, statistics has overlap withinformation science and computer science.

Statistic Today
During the 20th century, the creation of precise instruments for agriculturalresearch, public health concerns (epidemiology, biostatistics, etc.), industrialquality control, and economic and social purposes (unemployment rate,econometrics, etc.) necessitated substantial advances in statistical practices.Today the used of statistic has broadened far beyond its origin. Individualsand organizations use statistics to understand data and make informeddecisions throughout the natural and social sciences, medicines, business, andother area. Statistics are generally regarded not as the subfield of
mathematics but rather as a distinct, allied, field. Many universities maintainseparate mathematics and statistic departments. Statistic is also taught indepartment as diverse as psychology , education and public health.

(iii) Effect of long time consumption of packaged drinks on our health.
a) Tooth Decay: All soft drinks are acidic which corrodes the teeth by erodingits enamel. The high amount of sugar consumed through soft drinks lead tothe development of bacteria that attack the teeth thus aggravating dental
problems. People who drink three or more glasses of aerated drinks (gaseousdrinks) daily have much higher chances of dental decay, fillings and teethloss. Therefore, soft drinks contain acid and sugar that corrode and destroythe teeth in one shot.
b) Obesity: Soft drinks are mainly composed of filtered H2O, artificial additivesand refined sugar. Thus, they lack nutritional value and only add up caloriesthrough their refined sugar; therefore, they make you gain weight. But isshifting to "Diet Soft Drink" the solution? The fact is that diet soft drinkscontain aspartame (an artificial low-calorie sweetener). Although aspartamedoes not add up the calories it makes you feel hungrier and crave for food.The Food and Drug Administration (FDA) no longer allows foods containing
aspartame to be labeled as "weight reduction product ". Now it insists tolabel these products simply as "Diet Drink" or "Diet Food ". Research alsoshows that aspartame causes migraines, dizziness and more over it reducesyour memoryIt has been experimentally proved that soft drinks are one ofthe prominent reasons for obesity. The weight gain is directly related to theamount of soft drink that a person takes in. With every single can, peopleunknowingly add many extra calories to their body weight.
c) Diabetes :Another very common effect of soft drinks is diabetes. With everycan of soft drink, people add large amount of sugar in their body. Longhabitual intake of soft drinks can lead to ineffective insulin production frompancreases which consequently affect the sugar level in the body. Thisfurther leads to diabetes.
d) Osteoporosis: It has been proved that frequent consumption of soft drink canlead to weakening of the bones and osteoporosis. Soft drinks impair thecalcification of the growing bones in children.
e)Kidney stones: his fact may shock you, but is quite true. Researches haveproved that constant and habitual intake of soft drink can lead to kidney
stones formation. This happens because of the acidic and mineral radical
balance. The body triesto buffer the acidity caused by the soft drinks with thecalcium from the bones. This leads to calcium erosion, which ultimately gets
settled in the kidney in the form of stones.

f) Indigesdtion:Soft drink also leads to impaired digestive system. Soft drinkcontains phosphoric acid which competes with the hydrochloric acid present instomach and affects its functioning. The ineffectiveness of stomach leads to
undigested food which further causes indigestion and gassiness.
g) Dry throat :Soft drinks cause dehydration in the body. Both the sugar and caffeinecomponents of soft drinks are dehydrating agents. They both lead to excessurination, which makes you thirstier than before.
h) High blood pressure: Soft drinks have strong caffeine content. Caffeine causesirritability, restlessness, tension, high blood pressure, excessive urination and
other side effects. It is also believed that soft drinks increase blood pressure.
Some studies also claim that soft drink has harmful effects on liver.
The sweetener used in soft drinks is Aspartame. It is 200 times sweeter than normal sugar and is
far more harmful with many side effects.Next time, when head towards the refrigerator or a store
to satiate your thirst with a can of soft drink, make sure you remind yourself of all the sideeffects that gulping down the beverage will bring forth.

(b)(i) Golden RatioThe golden ratio has fascinated Western intellectuals of diverse interests for at
least 2,400 years. According to Mario Livio:
Some of the greatest mathematical minds of all ages, from Pythagoras and
Euclid in ancient Greece, through the medieval Italian mathematician Leonardo of
Pisa and the Renaissance astronomer Johannes Kepler, to present-day scientific
figures such as Oxford physicist Roger Penrose, have spent endless hours over this
simple ratio and its properties. But the fascination with the Golden Ratio is not
confined just to mathematicians. Biologists, artists, musicians, historians,
architects, psychologists, and even mystics have pondered and debated the basis of
its ubiquity and appeal. In fact, it is probably fair to say that the Golden Ratio has
inspired thinkers of all disciplines like no other number in the history of
mathematics.Ancient Greek mathematicians first studied what we now call the golden
ratio because of its frequent appearance in geometry. The division of a line into"extreme and mean ratio" (the golden section) is important in the geometry of
regular pentagrams and pentagons. The Greeksusually attributed discovery of this concept to Pythagoras or his followers. The
regular pentagram, which has a regular pentagon inscribed within it, was the
Pythagoreans' symbol.Euclid's Elements (Greek: ) provides the first known written definition ofwhat is now called the golden ratio: "A straight line is said to have been cut in
extreme and mean ratio when, as the whole line is to the greater segment, so is the
greater to the less." Euclid explains a construction for cutting (sectioning) a line "inextreme and mean ratio", i.e. the golden ratio. Throughout the Elements, several
propositions (theorems in modern terminology) and their proofs employ the golden
ratio. Some of these propositions show that the golden ratio is an irrational number.The name "extreme and mean ratio" was the principal term used from the
3rd century BC until about the 18th century.The modern history of the golden ratio starts with Luca Pacioli's De divina
proportione of 1509, which captured the imagination [citation needed] of artists,
architects, scientists, and mystics with the properties, mathematical and otherwise,
of the golden ratio.
Michael Maestlin, first to publish a decimal approximation of the goldenratio, in 1597.The first known approximation of the (inverse) golden ratio by a decimal fraction,
stated as "about 0.6180340," was written in 1597 by Michael Maestlin of the
University of Tbingen in a letter to his former student Johannes Kepler.Since the twentieth century, the golden ratio has been represented by the
Greek letter or (phi, after Phidias, a sculptor who is said to have employed it)

Futher Exploration
Material usually used to packaged drink.
Usually drinks are packaged using materials like plastic, aluminum, and glass in
different shapes and form. It usually come packaged in bottle ( plastic or glass )
and can ( aluminum ) .
Plastic
Composition of Plastic
Most organic polymers are plastics. The vast majority of these polymers are based on
chains of carbon atoms alone or with oxygen, sulfur, or nitrogen as well. The backboneis that part of the chain on the main "path" linking a large number of repeat units
together. To customize the properties of a plastic, different molecular groups "hang"
from the backbone (usually they are "hung" as part of the monomers before linking
monomers together to form the polymer chain). The structure of these "side chains"
influence the properties of the polymer. This fine tuning of the properties of the polymer
by repeating unit's molecular structure has allowed plastics to become an indispensable
part of the twenty-first century world
Additives of plastic
. Most plastics contain other organic or inorganic compounds blended in. The amount of
additives ranges from zero percentage for polymers used to wrap foods to more than
50% for certain electronic applications. The average content of additives is 20% by
weight of the polymer. Fillers improve performance and/or reduce production
costs. Stabilizing additivesinclude fire retardants to lower the flammability of the
material. Many plastics contain fillers, relatively inert and inexpensive materials that
make the product cheaper by weight. Typically fillers are mineral in origin, e.g., chalk.
Some fillers are more chemically active and are called reinforcing agents. Since many
organic polymers are too rigid for particular applications, they are blended
with plasticizers, oily compounds that confer improved rheology. Colorants are of coursecommon additives, although their weight contribution is small. Many of the controversies
associated with plastics are associated with the additives.
Recycling of Plastic
Plastic can be recycled. There are about 50 types of plastic used in the industry. Theplastics industry has developed a coding system to help consumers identify different

types of plastic resins used in packaging. The codes can be found on the bottom ofmost plastic containers. Plastic Bottles:The material used to make plastic soda bottles(polythylene terephthalate or PET) is recyclable. These bottles are coded with thenumber 1 and the letters PETE. About 30 percent of all PET bottles sold are recycledinto a variety of products.
Glass
Composition of Glass
Most glass is a mixture of silica obtained from beds of fine sand or from pulverized
sandstone; an alkali to lower the melting point, usually a form of soda or, for finer glass,
potash; lime as a stabilizer; and cullet (waste glass) to assist in melting the mixture. The
properties of glass are varied by adding other substances, commonly in the form of
oxides, e.g., lead, for brilliance and weight; boron, for thermal and electrical resistance;
barium, to increase the refractive index, as in optical glass; cerium, to absorb infrared
rays; metallic oxides, to impart color; and manganese, for decolorizing. The termcrystal glass, derived from rock crystal, was at first applied to clear, highly refractive
glass; it has come to denote in the trade a high-grade, colorless glass and is sometimes
applied to any fine hand-blown glass.
Additivities of Glass
Glass also contains additives. Additives are used in glass coloring and color marking.
Glass coloring and color marking may be obtained by addition of coloring ions,
precipitation of nanometer sized colloides (so-called striking glassessuch as "ruby
gold" or red "selenium ruby" by colored inclusions (as in milk glass and smoked glass),by light scattering (as in phase separated glass), by dichroic coatings (seedichroic
glass), or by colored coatings. The additives used in glass will not affect the user.
Recycling of Glass
Glass is endlessly recyclable, and most glass bottles and jars produced contain at least 25%
recycled glass which also requires 75% less energy to produce than glass made from new
materials. In recycling glass . the glass is sorted by colour and washed to remove impurities The
glass is then crushed and melted, then moulded into new products such as bottles and jars. Or
it may be used for alternative purposes such as brick manufacture or decorative uses.The glassis then sent back to the shops ready to be used again.

Aluminum
Composition of aluminum can
Aluminum is a silvery white member of the boron group of chemical elements. It has the
symbol Al, and its atomic number is 13. It is not soluble in water under normalcircumstances. Aluminum metal is so chemically reactive that native specimens are rare
and limited to extreme reducing environments. Instead, it is found combined in over
270 different minerals.[4]The chief ore of aluminum is bauxite. It is remarkable for the
metal's low density and for its ability to resist corrosion due to the phenomenon
of passivation.
Additives of aluminum can
There are no additives in aluminum can .
Recycling of aluminum can
Aluminum is a sustainable metal and can be recycled over and over again. A can is
generally turned into a new can and back on store shelves within 60 days. Cans are
usually available through curbside pickup or community drop-off locations nationwide.

Eco-friendly Material for pakaging drinks
The term eco-friendly is used to describe activities which are good for the environment. It is a
shortening of ecologically friendly, and you may also hear terms like environmentally
friendly or green used to describe similar activities. There are a range of ways in which
activities can be eco-friendly, ranging from products which are constructed in an
environmentally friendly way to making lifestyle changes which are designed to benefit the
environment. The most eco-friendly material for packaging drinks is glass.
Glass is more environmentally friendly because it doesn't use fossil fuels to produce, however
as far as recycling is concerned it is difficult to say. Conclusive life-cycle studies are yet to be
fully analyzed. However glass can be more easily returned to its natural state of composite
sand. Whereas plastic takes on average 2000 years to biodegrade.Meanwhile, aluminum can
also be recycle. But it cannot be reuse again like glass. It has to undergo several process in the
treatment plant to be able to be used again. This require more energy .
On the other hand, glass is more enviromentally friendly because glass could be used over and
over again. It is long lasting and Glass is 100% recyclable and can be recycled endlessly with no
loss in quality or purity. Glass recycling is a closed loop system, creating no additional waste or
by-products. Glass is a mono-material, meaning it is not made up of several different materials.

Conclusion
After doing research, answering questions, drawing graphs and some
problem solving, I saw that the usage of statistics is important in daily life. It
is not just widely used in markets but also in interpreting the condition of the
surrounding like the air or the water. Especially in conducting an air-pollution
survey. In conclusion, statistics is a daily life necessities. Without it, surveys
cant be conducted, the stock market cant be interpret and many more.
Statistics are a major staple of our world today. They are used in practically
any situation and help improve our overall lifestyle. Statistics change the way
we think about tomorrow and the way we live today and without them. So,
we should be thankful of the people who contribute in the idea of statistics.
