Test the following hypotheses by using the χ2 goodness of fit
test.
H0: pA = 0.2, pB = 0.4, and pC = 0.4
Ha: The population proportions are not pA = 0.2, pB = 0.4, and
pC = 0.4
A sample of size 200 yielded 40 in category A, 120 in category
B, and 40 in category C. Use = .01 and test to see whether the
proportions are as stated in H0.
