compute confidence intervals of average prestige scores for each

1. Compute the T-test to answer the question: "Do males and females differ with respect to average miles students live from school in the whole population from which this sample was drawn?"

points of these proportions if we generalize them to the whole
population from which this sample was drawn?"
