13.34 Tuna, continued Refer to Exercise 13.33. 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 x and x2 change. This can only happen when = = B3 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 13.33.
