Two different simple random samples are drawn from two different populations. The first sample consists of
40 people with 21 having a common attribute. The second sample consists of
2000 people with 1429 of them having the same common attribute. Compare the results from a hypothesis test of
p 1=p2 (with a 0.05 significance level) and a 95% confidence interval estimate of p 1-p2.
What are the null and alternative hypotheses for the hypothesis test?
What is the test statistic?
What is the critical value?
What is the conclusion based on the hypothesis test?
What is the 95% confidence level?
What is the conclusion based on the confidence interval?
How do the results from the hypothesis test and the confidence interval compare?
