Suppose we have a multinomial population with four categories: A, B, C, and D. The null hypothesis is that the proportion of items is the same in every category. The null hypothesis is
H0: pA = pB = pC = pD = .25
A sample of size 300 yielded the following results.
A: 85 B: 95 C: 50 D: 70
Use α = .05 to determine whether H0 should be rejected. What is the p-value?
