Two different simple random samples are drawn from two different populations. the first sample consists of 20 people with 9 having a common attribute. the second sample consists of 2100 people with 1492 of them having the same common attribute. compare the results from a hypothesis test of p 1equalsp 2 (with a 0.05 significance level) and a 95% confidence interval estimate of p 1minusp 2.

Step-by-step explanation:

The confidence interval for the difference of two population proportion is given by :-

Given : The first sample consists of 20 people with 9 having a common attribute.
