With reference to Exercise 12 11 (a) Test H0 p1, 0 versus H1 l 0 with a 05 (b) Test H0 32 0 versus H1 2 0 with a 05 (c) Estimate the expected y value corresponding to x1, 3 2 and x2 200 (d) Construct a 90 confidence interval for the intercept 0

Question: With reference to Exercise 12.11: (a) Test H0 : p1, =0 versus H1 : l 0 with a = .05. (b) Test H0: 32

With reference to Exercise 12.11:
(a) Test H0 : p1, =0 versus H1 : βl ≠ 0 with a = .05.
(b) Test H0: 32 = 0 versus H1 : β2 ≠ 0 with a = .05.
(c) Estimate the expected y value corresponding to x1, = 3.2 and x2 = 200.
(d) Construct a 90% confidence interval for the intercept β0.
