# Test the following hypotheses by using the χ 2 goodness of fit test. H 0 : p A = .40, p B = .40, and p C = .20 H a : The population proportions are not p A = .40, p B = .40, and p C = .20 A sample of size 200 yielded 60 in category A, 120 in category B, and 20 in category C. Use α = .01 and test to see whether the proportions are as stated in H 0 . a. Use the p -value approach. b. Repeat the test using the critical value approach.
