Exercise 11-7 gave 20 observations on y = highway gasoline mileage and x = engine displacement.
(a) Test for significance of regression using a = 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: B1 = – 0.05 versus H1: B1 < -="" 0.05="" using="" a="0.01" and="" draw="" conclusions.="" what="" is="" the="" p-value="" for="" this="">
(d) Test the hypothesis H0: B0 = 0 versus H1: B0 = 0 using a = 0.01. What is the P-value for this test?
