Consider the data from Exercise 11-6 on y highway gasoline mileage and x engine displacement.

(a) Test for significance of regression using  0.01. Find the P-value for this test. What conclusions can you reach?

(b) Estimate the standard errors of the slope and intercept.

(c) Test H0: 1 0.05 versus H1: 1  0.05 using 

0.01 and draw conclusions. What is the P-value for this test?

(d) Test the hypothesis H0: 0 0 versus H1: 0 0 using

 0.01. What is the P-value for this test?
