Two different simple random samples are drawn from two different
populations. The first sample consists of 20 people with 11 having
a common attribute. The second sample consists of 2000 people with
1430 of them having the same common attribute. Compare the results
from a hypothesis test of p1=p2 ​(with a 0.05 significance​ level)
and a 95​% confidence interval estimate of p 1minus−p2.
