Textbook Question

Chapter 12.1, Problem 1E

Test the following hypotheses for a multinomial probability distribution by using the X 2 goodness of fit test.
H 0 : p A = .40 , p B = .40 , and p C = .20
H 0 : The probabilities 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 probabilities are as stated in H 0 .
a. Use the p-value approach.
b. Repeat the test using the critical value approach.
