Nkechi took a random sample of 10 countries to study fertility rate (babies per woman) and life expectancy (in years). She noticed a strong negative linear relationship between those variables in the sample data. Here is computer output from a least-squares regression analysis for using fertility rate to predict life expectancy: Predictor Coef SE Coef T P
Constant 89.70 1.63 54.87 0.00
Fertility -5.97 0.59 -10.18 0.00
S = 1.91
R-sq = 92.8%
Use this model to predict the life expectancy of a country whose fertility rate is 2 babies per woman. You may round your answer to the nearest whole number of years.
