The data shown in the table are the numbers of years of formal education of the fathers and mothers of a sample of 29 statistics students at a small community college in an area with many recent immigrants. (The means are both about 8, and the standard deviations are both about 4.6.) The scatterplot (not shown) suggests a linear trend.
a. Find and report the regression equation for predicting the mother’s years of education from the father’s. Then find the predicted number of years for the mother if the father has 12 years of education, and find the predicted number of years for a mother if the father has 4 years of education.
