Two different simple random samples are drawn from two different populations. The first sample consists of 20 people with 10 having a common attribute. The second sample consists of 2200 people with 1597 of them having the same common attribute. Compare the results from a hypothesis test of p1= p2 ​(with a 0.01 significance​ level) and a 99​% confidence interval estimate of p1− p2.
