1. First, we need to find the critical value of z. Since this is a right-tailed test (H1: p > 0.

Question

In a hypothesis test with hypotheses H0: p ≤ 0.39 and H1: p > 0.39, a random sample of size 505 produced a sample proportion of 0.4500. The test is to be made at the 5% significance level. What is the critical value of z? 1.96 1.645 2.12 2.72 What is the value of the test statistic, z, rounded to three decimal places? What is the p-value for this hypothesis test, rounded to four decimal places? Should you reject or fail to reject the null hypothesis in this test? Fail to reject. Reject.
