Question:

Is it defense or offense that wins football games? Consider the following portion of data, which includes a team’s winning record (Win in %), the average number of yards gained, and the average number of yards allowed during a recent NFL season.

a. Compare two simple linear regression models where Model 1 predicts Win as a function of Yards Gained and Model 2 predicts Win as a function of Yards Allowed.

b. Estimate a linear regression model, Model 3, that applies both Yards Gained and Yards Allowed to forecast Win. Is this model an improvement over the other two models? Explain.
