5 Things that can effect the survival rate of sea turtles. The amount of lighting can effect the seas turtles by

distracting them and setting them off track. There can be predators in the area that can eat them

such as: Pigeons, Raccoons and people also. There can also be people that come and steal them

for souvenirs. Then there are vehicles that can run over them and

kill them. Lastly there can be that it is a populated beach so

people stick there umbrellas in the nest or walk all over the nest.

Average of Sharp-Nosed Sharks

Probability: Probability: Is a way to measure the

chances that something will occur in relation to the possible alternatives.

Corals Scientific Notification

Kingdom: Animalia Phylum: Cnidaria Class: Anthozo

Things That Can Affect Probability Of Coral Survival: Water temperature is one big thing that lower the survival rate of coral

reefs.(70-83 degrees fare height, 21-28 degrees Celsius) There can be no current where the coral decides to stay. There can be no sunlight where the coral stays. Because where it

stays is to deep.(coral reefs live in shallow water, maximum up to 56ft.

There can be oil spills (example: The spill in the Gulf Of Mexico) the oil can poison the coral and then they die.

And lastly pollution can affect the coral reefs (example: Fish nets grab onto the coral, and then if there is current will tear pieces off the coral)

Also when coral reefs die they eventually turn white like so;

Variance

Variance: Is a value that describes how far away the number is from the mean.

It is different from the mean because the mean is the average of a group of numbers. But the variance is the statistical explanation on how far away is the number from the mean.

T-TEST The T-TEST is a equation that you need to calculate the t-

statistics is one designed to test whether there is a significant difference between the means of two independent samples ,those of your treatment and control groups.

A t-test can be used to compare two means or proportions. The t-test is appropriate when all you want to do is to compare means.

The degrees of freedom are the number of extra numbers you need to specify your data completely, after you have provided a summary of your data.

The Chi-Square test is a statistical test mostly used to compare observed data with data we would expect to obtain according to a specific hypothesis.

We reject the null hypothesis, and accept the alternative hypothesis that there is a significant difference in survival rates between beach sites.
