Refer to Exercise 13.32. The hypothesis tested in Chapter 11-that the average prices for the four types of tuna are the same-is equivalent to saying that E(y) will not change as x1 and x2 change. This can only happen when β1 = β2 = β3 = 0. Use the MINITAB printout for the one-way ANOVA shown below to perform the test for equality of treatment means. Verify that this test is identical to the test for significant regression in Exercise 13.32.
