You may need to use the appropriate appendix table or technology to answer this question. Consider the hypothesis test. Ho: P1 - P2 so Ha: P1 - P2 > 0 The following results are for independent samples taken from the two populations. Sample 1 Sample 2 71 = 200 n, = 300 P1 = 0.22 P2 = 0.16 (a) Calculate the test statistic. (Round your answer to two decimal places.) What is the p-value? (Round your answer to four decimal places.) p-value = (b) With a = 0.05, what is your hypothesis testing conclusion? O Reject Ho. There is insufficient evidence to conclude that P1 - P2 > 0. O Reject Ho. There is sufficient evidence to conclude that P , - P2 > 0. O Do not Reject Ho. There is sufficient evidence to conclude that P 1 - P2 > 0. O Do not reject Ho. There is insufficient evidence to conclude that P, - P2 > 0. Need Help? Read It Watch It Master It
