a. In part (c) of exercise 10, an estimated regression equation was developed relating the proportion of games won given the percentage of field goals made by the team, the proportion of three-point shots made by the team’s opponent, and the number of turnovers committed by the team’s opponent. What are the values of R2 and R2a?
b. Does the estimated regression equation provide a good fit to the data? Explain.
