Life expectancy 2013 Data for 26 Western Hemisphere countries can be used to examine the association between life expectancy and the birth rate (number of births per 1000 population).

a) Create a scatterplot relating Life Expectancy to Birth Rate and describe the association. Are the regression assumptions satisfied?

b) Is there an outlier? If so, set it aside and identify it before computing the regression.

c) Find the equation of the regression line with the outlier removed.

d) Make a plot of the residuals and comment.

e) Is the line an appropriate model?.

f) Interpret the value of R2.
g) If government leaders want to increase life expectancy, should they encourage women to have fewer children?
Explain.
