Consider the NFL data in Exercise 12-17.

(a) Test for significance of regression using 0.05. What is the P-value for this test?

(b) Conduct the t-test for each regression coefficient. Using

0.05, what conclusions can you draw about the variables in this model?

(c) Find the amount by which the regressor x2 (TD percentage) increases the regression sum of squares, and conduct an F-test for H0: 2 0 versus H1: 2 0 using

0.05. What is the P-value for this test? What conclusions can you draw?
