Assume we want to use a .05 significance level to test the claim that P1<p2. It we want to test that claim by using a confidence interval, what confidence interval should we use? If we test the claim in part a using the sample data in exercise 1, we get this confidence interval: -0.000508<p1-p2<-0.000309. What does this confidence interval suggest about the claim? In general, when dealing with inferences for two population proportions, which two of the following are equivalent: Confidence interval method; P-value method; critical value method?
