3.) The World Bank collects information on the life expectancy of a person in each country ("Life expectancy at," 2013) and the fertility rate per woman in the country ("Fertility rate," 2013). The data for 24 randomly selected countries for the year 2011 are in table # 10.1.7. Create a scatter plot of the data and find a linear regression equation between fertility rate and life expectancy. Then use the regression equation to find the life expectancy for a country that has a fertility rate of 2.7 and for a country with fertility rate of 8.1. Which life expectancy that you calculated do you think is closer to the true life expectancy? Why?

3.) The World Bank collects information on the life expectancy
of a person in each country ("Life expectancy at," 2013) and
the fertility rate per woman in the country ("Fertility rate,"
2013). The data for 24 randomly selected countries for the year
2011 are in table #10.1.7. Create a scatter plot of the data and
find a linear regression equation between fertility rate and
life expectancy. Then use the regression equation to find the
life expectancy for a country that has a fertility rate of 2.7 and
for a country with fertility rate of 8.1. Which life expectancy
that you calculated do you think is closer to the true life
expectancy? Why?
