Two different simple random samples are drawn from two different populations. The first sample consists of 40 people with 20 having a common attribute. The second sample consists of 2200 people with 1559 of them having the same common attribute. Compare the results from a hypothesis test of p 1 = p 2 (with a 0.05 significancelevel) and a 95% confidence interval estimate of p 1−p 2.
What are the null and alternative hypotheses for the hypothesistest?
Identify the test statistic. nothing (Round to two decimal places as needed.)
Identify the critical value(s). (Round to three decimal places as needed. Use a comma to separate answers as needed.)
