An online poll asked: "Do you believe the Loch Ness monster exists?" Among 21,901 responses, 61% 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. O A. Ho: p > 0.5 H1: p = 0.5 Credit: O B. Ho: p = 0.5 stion 3 H, : p 0.5A data set includes data from student evaluations of courses. The summary statistics are n = 90, x = 3.94, s = 0.55. Use a 0.10 significance level to test the claim that the population of student course evaluations has a mean equal to 4.00. Assume that a simple random sample has been selected. Identify the null and alternative hypotheses, test statistic, P-value, and state the final conclusion that addresses the original claim. What are the null and alternative hypotheses? O A. Ho: H# 4.00 O B. Ho: H = 4.00 Hy: H = 4.00 H, : u> 4.00 O C. Ho: H= 4.00 OD. Ho: H= 4.00 Hy: u # 4.00 H1 : u
