A development officer at a large university believes that the amount of money donated to the general fund by alumni each year is linearly related to the football team's winning percentage. A random sample of Division I football teams was selected. The winning percentage (x) and subsequent alumni donation amount (y, in millions of dollars) are given in the following table.
a. Construct a scatter plot for these data.
b. Find the estimated regression line. Add a graph of the estimated regression line to the scatter plot in part (a).
c. Find an estimate of an observed value of the donation amount for a football team with a winning percentage of 75%.
