An online poll asked: "Do you believe the Loch Ness monster exists?" Among 22185 responses, 69%were "yes." Use a 0.10 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. A. H0: p>0.5 H1: p=0.5 B. H0: p=0.5 H1: p<0.5 C. H0: p=0.5 H1: p>0.5 D. H0: p=0.5 H1: p≠0.5 Part 2 Identify the test statistic for this hypothesis test. The test statistic for this hypothesis test is enter your response here. (Round to two decimal places as needed.) Part 3 Identify the P-value for this hypothesis test. The P-value for this hypothesis test is enter your response here. (Round to three decimal places as needed.)

The P-value for this hypothesis test is
enter your response here.
(Round to three decimal places as needed.)
Part 4
Identify the conclusion for this hypothesis test.
A. fail to reject There is sufficient evidence to warrant rejection of the claim that most people believe that the Loch Ness monster exists
B. Fail to reject. There is not sufficient evidence to warrant rejection of the claim that most people believe that the Loch Ness monster exists.
C. reject. There is sufficient evidence to support the claim that most people believe that the Loch Ness monster exists.
D. reject. There is not sufficient evidence to support 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?
A.Since the sample size is sufficiently large, the conclusion is valid.
