Textbook Problem

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.
