f. (0.125 points) Interpret the coefficient of determination in Model 1.

g. (0.375 points) Do these results support the idea that population health (as measured by life expectancy) is affected by education levels (as measured by % literate)? Explain your answer in no more than a few sentences. Be sure to incorporate direction, magnitude, and statistical significance of the association in your explanation.
