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 2200 people with 1581 of them having the same common attribute. Compare the results from a hypothesis test of p 1 equalsp 2 (with a 0.05 significance level) and a 95% confidence interval estimate of p 1minusp 2. A. Identify the test statistic. (Round to two decimal places as needed.) B. Identify the critical value(s). (Round to three decimal places as needed. Use a comma to separate answers as needed.) C. The 99% confidence interval is less than left parenthesis p 1 minus p 2 right parenthesis less than (Round to three decimal places as needed.)
