Two different simple random samples are drawn from two different populations. The first sample consists of 30 people with 14 having a common attribute. The second sample consists of 1800 people with 1292 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 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 null hypothesis.

There is ▼ evidence to conclude that p 1not equals≠p 2. The 95​% confidence interval is less than = less than or equals≤ p 2​, and the confidence interval suggests that p 1 ▼
