Construct the indicated confidence interval for the difference between population proportions Assume that the samples are independent and that they have been randomly selected. Be sure to provide the (1) Null & Alternative Hypotheses, (2) Test Statistic, (3) P-value (or critical value), and (4) concluding statements.

x1 = 15, n1 = 50 and x2 = 23, n2 = 60;

Construct a 90% confidence interval for the difference between population proportions p1 - p2.
