When the necessary conditions are met, a two-tail test is being conducted to test the difference between two populations proportions. The two sample proportions are P1 = 0.25 and P2 = 0.20 and the standard error of the sampling distribution of P1 - P2 is 0.04. the caculated value of the test statistic will be
