You may need to use the appropriate appendix table or technology to answer this question. Consider the hypothesis test. Ho: P1 - P2 0 The following results are for independent samples taken from the two populations. Sample 1 Sample 2 n1 = 200 n2 = 300 = 0.24 P2 P1 = 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? Reject Ho. There is insufficient evidence to conclude that p, - p2 > 0. Reject Ho. There is sufficient evidence to conclude that p, - p, > 0. Do not reject Ho. There is insufficient evidence to conclude that p, - p, > 0. Do not Reject Ho: There is sufficient evidence to conclude that p, - p, > 0.
Find the value of the standard score, z, and determine whether to reject the null hypothesis at a 0.10 significance level. Is the alternative hypothesis supported? Ho: p= 19.6 seconds, H: p> 19.6 seconds, n = 121, x=20 5 seconds, o = 2.0 seconds a The value of the standard score is (Round to two.decimal places as needed.)
An online poll asked: "Do you believe the Loch Ness monster exists?" Among 20,926 responses, 65% were "yes." Use a 0.01 significance level to test the claim that most people believe that the Loch Ness monster exists. How is the conclusion affected by the fact that Internet users who saw the question could decide whether to respond? Identify the null and alternative hypotheses for this test. Choose the correct answer below. O A. Ho: p>0.5 H:p=0.5 O B. Ho: p= 0.5 H4:p0.5 O D. Ho: p=0.5 H:p#0.5 Identify the test statistic for this hypothesis test. The test statistic for this hypothesis test is (Round to two decimal places as needed.) Identify the P-value for this hypothesis test. The P-value for this hypothesis test is (Round to three decimal places as needed.) Identify the conclusion for this hypothesis test. O A. Reject Ho. There is not sufficient evidence to warrant rejection of the claim that most people believe that the Loch Ness monster exists. B. Reject Ho. There is sufficient…
