Consider the National Football League data in Exercise 11-4.
(a) Test for significance of regression using a = 0.01. Find the P-value for this test. What conclusions can you draw?
(b) Estimate the standard errors of the slope and intercept.
(c) Test (using a = 0.01) H0: B1 = - 0.01 versus H1: B1 = 0.01. Would you agree with the statement that this is a test of the claim that if you can decrease the opponent’s rushing yardage by 100 yards the team will win one more game?
