Consider the data from Exercise 11-6 on y = steam usage and x = average temperature.
(a) Test for significance of regression using a = 0.01. What is the P-value for this test? State the conclusions that result from this test.
(b) Estimate the standard errors of the slope and intercept.
(c) Test the hypothesis H0: B1 = 10 versus H1: B1 ( 10 using a = 0.01. Find the P-value for this test.
(d) Test H0: B0 = 0 versus H1: B0 = 0 using a = 0.01. Find the P-value for this test and draw conclusions.
