Question

You wish to test the following hypotheses at a significance level of α = 0.005 . H 0 : p 1 = p 2 H A : p 1 > p 2 You obtain 29 successes in a sample of size n 1 = 248 from the first population. You obtain 59 successes in a sample of size n 2 = 595 from the second population. Suppose that all assumptions are met, so that the difference in sample proportions follows a normal distribution. What is the test statistic for this sample? (Report answer accurate to two decimal places.) z =

What is the p -value for this sample? (Report answer accurate to four decimal places.) p -value =
