Two different simple random samples are drawn from two different populations. The first sample consists of 30 people with 15 having a common attribute. The second sample consists of 1900 people with 1379 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.
Find hypothesis, test statistic, critical value, p value, and 95% CL.
