what would the standardized test stat be?

Decide whether the normal sampling distribution can be used. If it can be used, test the claim about the difference between two population proportions p, and p2 at the given level of significance a using the given sample statistics. Assume the sample statistics are from independent random samples. Claim: P1 = P2, a = 0.05 Sample statistics: X1 = 20, n1 = 116 and X2 = 89, n2 - 218 O C Ho: P1 * P2 Ha: P1 - P2 O D. Ho- P1
