Pigskin: In football, a turnover occurs when a team loses possession of the ball due to a fumble or an interception. Turnovers are bad when they happen to your team, but good when they happen to your opponent. The turnover margin for a team is the difference (Turnovers by opponent €” Turnovers by team). The following table presents the turnover margin and the total number of wins for each team in the Southeastern Conference (SEC) in a recent season.

a. Compute the least-squares regression line for predicting team wins from turnover margin.
b. Construct a residual plot. Verify that a linear model is appropriate.
c. Which teams won more games than would be predicted from their turnover margin?
