population

Population Growth. Consider the following table showing percentage change in population and birth rate (per 1,000 of population) for 10 states over a period of 10 years.State Percentage change in population Birth rate

Nevada 50.1% 16.3

Califonia 25.7% 16.9

New Hampshire 20.5% 12.5

Utah 17.9 % 21.0

Colorado 14.0% 14.6

Minnesota 7.3% 13.7

Montana 1.6% 12.3

Illinois 0% 15.5

Iowa -4.7% 13.0

West Virginia -8.0% 11.4

a. Construct a scatterplot for the data.

b. Briefly characterize the correlation in words and estimate the correlation coefficient.

c. Overall, does birth rate appear to be a good predictor of a state’s population growth rate? If not, what other factor(s) may be affecting the growth rate?

2. Next, write a complete solution, showing all steps used in solving the problem. Attach any graphs that you might need using Add/Remove. Explain each step as if you were the expert explaining it to a novice.
