Here are data on the years of schooling completed, x, and annual income, y, (in thousands of dollars) for a sample of 18 40-year old men.

A scatterplot (don't do it) shows a generally linear relation, but with considerable scatter about the line of best fit A. What percent of the observed variation in income is explained by the straight line relation between income and education? (10 pts) B. Is there strong evidence that there is a straight line relation between education and income? Test the claim using alpha = .05. (17 pts)
