Step-by-step explanation. For first sample, number of success and failures is not at least. Success = 16 > 10. and. failure = 25 - 16 = 9 < 10 (condition failed) Therefore, we cannot use the method because the condition of large count or success failure is not satisfied.

The z-test is a statistical test for comparing the proportions from two populations. It can be used when the samples are independent, n1ˆp1 ≥ 10, n1ˆq1 ≥ 10, n2ˆp2 ≥ 10, and n2ˆq2 ≥ 10. The formula for the z-test statistic is: z = (ˆp1 − ˆp2) − (p1 − p2) √(ˆp ⋅ ˆq( 1 n1 + 1 n2))The conditions we need for inference on one proportion are: Random: The data needs to come from a random sample or randomized experiment.
