Random samples from two binomial populations yielded the following statistics:

a. Calculate the p-value of a test to determine whether we can infer that the population proportions differ.

pN 1 = .45 n1 = 100 pN 2 = .40 n2 = 100

b. Repeat part

(a) increasing the sample sizes to 400.

c. Describe what happens to the p-value when the sample sizes increase.
