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 altemative hypotheses for this test. Choose the correct answer below. OA. Ho: p>0.5 H:p=0.5 OB. Ho:p=0.5 H:p<0.5 OC. Ho: p=0.5 H:p>0.5 OD. Hg: p=0.5 H:p40.5 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. OA Reject H. There is not sufficient evidence to warrant rejection of the claim that most people believe that the Loch Ness monster exists. OB. Reject Hg. There is sufficient evidence to support the claim that most people believe that the Loch Ness monster exists O C. Fail to reject H. There is not sufficient evidence to warrant rejection of the claim that most people beleve that the Loch Ness monster exists. Click to select your answer(s).
