What is the test statistic?

What is P-value?

Reject or Fail to reject?

Are they any issues with the way the sample was obtained?

An online poll asked: "Do you believe the Loch Ness monster exists?" Among 20,656 responses, 66% were "yes." Use a 0.05 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.** - A. \( H_0: p = 0.5 \) \( H_1: p < 0.5 \) - B. \( H_0: p > 0.5 \) \( H_1: p = 0.5 \) - C. \( H_0: p = 0.5 \) \( H_1: p \neq 0.5 \) - D. \( H_0: p = 0.5 \) \( H_1: p > 0.5 \) (Correct option) --- **Identify the test statistic for this hypothesis test.** The test statistic for this hypothesis test is [ ]. (Round to two decimal places as needed.)
