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:
\begin{tabular}{lrrrrr}
Predictor & Coef & SE Coef & T & P \\
\hline Constant & 89.70 & 1.63 & 54.87 & 0.00 \\
Fertility & -5.97 & 0.59 & -10.18 & 0.00 \\
S & R-sq & & & \\
\hline
\end{tabular}
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.
years
