Two different simple random samples are drawn from two different populations. The first sample consists of 30 people with 16 having a common attribute. The second sample consists of 1800 people with 1310 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.        Identify the test statistic.   enter your response here ​(Round to two decimal places as​ needed.)
