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 1900 people with 1353 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.
(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.)
What is the conclusion based on the hypothesis test?
The test statistic is
the critical region, so
The 99% confidence interval is < (P₁-P₂) <
(Round to three decimal places as needed.)
