Exercise 11-8 gave 13 observations on y = green liquor Na2S concentration and x = production in a paper mill.
(a) Test for significance of regression using a = 0.05. Find the P-value for this test.

(b) Estimate the standard errors of the slope and intercept.
(c) Test H0: B0 = 0 versus H1: B0 = 0 using a = 0.05. What is the P-value for this test?
