7. Suppose 222 subjects are treated with a drug that is used to treat pain and 52 of them developed nausea. Use a 0.05 significance level to test the claim that more than 20% of users develop nausea. Identify the null and alternative hypotheses for this test. Choose the correct answer below. 'A. Ho: p=0.20 H;: p>0.20 B. Ho: p= 0.20 H,:p< 0.20 OC. Ho: p= 0.20 H,: p#0.20 Họ: p>0.20 H1: p= 0.20 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 support of the claim that more than 20% of users develop nausea. O B. Reject Ho. There is sufficient evidence to warrant support of the claim that more than 20% of users develop nausea. OC. Fail to reject Hg. There is not sufficient evidence to warrant support of the claim that more than 20% of users develop nausea. O D. Fail to reject Ho. There is sufficient evidence to warrant support of the claim that 200
