Assume that you plan to use a significance level of α = 0.05 to test the claim that p1 = p2, use the given sample sizes and numbers of successes to find the pooled estimate. round your answer to the nearest thousandth.

Since the data is insufficient. Let us denote that n1 = 100, n2 = 100X1 = 38. X2 = 40

So looking for the p value:

p = (38 + 40) / (100 + 100) = 0.39

z = (38/100 - 40/100) / √ (0.39 * (1-0.39) * (1/100 + 1/100)) = - 0.2899

P-value = P (|z| > 0.2899) = 0.7718
