SORU:

Covering the hypothesis test of the difference between two population proportions, and these parameters are depicted with p1 and p2, a sample proportion from each population is utilized to realize the z-test for the difference between two population proportions. The basic assumption of the test considered here is that there is no difference between the population proportions. Then, define the hypotheses for difference between two population proportions for left sided test and express null and alternative hypothesis.
