Unit 7 Linear Modeling Project
Introduction
•My projects about an estimated number of deaths in each city.
• I chose this topic because I was interested to see if there was a trend and see what cities came up the highest.
•The data I found was the population of different cities from the year 2010.
Data
Population Deaths
New York City: 8,175,133 65,360
Los Angeles: 3,792,621 30,322
Chicago: 2,695598 21,551
Houston: 2,100,263 16,791
Phoenix: 1,445,632 11,557
San Antonio: 1,327,407 10,612
Jacksonville: 821,784 6,570

Data Explanation • The higher the population the higher the
deaths.
• The lower the population the lower the deaths.
•Number of deaths is never higher than the population.
• I used the equation x/100,000 · 799.5 to find the estimated amount of deaths of each city. (I got this death rate formula from the CDC website http://www.cdc.gov/nchs/fastats/deaths.htm)
•A huge city like New York City has almost ten times the amount of deaths of a smaller city like Jacksonville.

Calculations
Prediction & Discussion
• I predict that if a city that has a population of about 5 million, then that city had about 39,975 deaths in 2010.
• The x intercept is -72.233125. Which is unrealistic because this would mean that 0 deaths would happen if the population is -72.233125. The population can never be negative.
• The y intercept is 0.577865. Which is unrealistic because that means that about half a death would happen if the population is 0. If there is no population there can’t be any type of deaths.
