Consider a drug testing company that provides a test for marijuana usage. Among 283 tested subjects, results from 27 subjects were wrong (either a false positive or a false negative). Use a 0.10 significance level to test the claim that less than 10 percent of the test results are wrong. Identify the null and alternative hypotheses for this test. Choose the correct answer below. OA. Ho: P = 0.1 H1 : p = 0.1 OB. Ho: P = 0.1 Hy : p #0.1 O C. Ho: P = 0.1 H, : p 0.1 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. Fail to reject Ho. There is sufficient evidence to warrant support of the claim that less than 10 percent of the test results are wrong. O B. Reject Ho. There is sufficient evidence to warrant support of the claim that less than 10 percent of the test results are wrong. O C. Reject Ho. There is not sufficient evidence to warrant support of the claim that less than 10 percent of the test results are wrong. O D. Fail to reject Ho. There is not sufficient evidence to warrant support of the claim that less than 10 percent of the test results are wrong.In one study of smokers who tried to quit smoking with nicotine patch therapy, 35 were smoking one year after treatment and 31 were not smoking one year after the treatment. Use a 0.05 significance level to test the claim that among smokers who try to quit with nicotine patch therapy, the majority are smoking one year after the treatment. Do these results suggest that the nicotine patch therapy is not effective? Identify the null and alternative hypotheses for this test. Choose the correct answer below. O A. Ho: P = 0.5 H1 : p = 0.5 O B. Ho: p = 0.5 H,: p 0.5 H, : p = 0.5 O D. Ho: P = 0.5 H1 : p # 0.5 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. O A. Reject Ho- There sufficient evidence to warrant support of the claim that the majority are smoking one year after the treatment. O B. Fail to reject Ho. There insufficient evidence to warrant support of the claim that the majority are smoking one year after the treatment. O C. Reject Ho- There insufficient evidence to warrant support of the claim that the majority are smoking one year after the treatment. O D. Fail to reject Ho. There sufficient evidence to warrant support of the claim that the majority are smoking one year after the treatment. Do these results suggest that the nicotine patch therapy is not effective? Since there is evidence to support the claim that the majority are smoking one year after the treatment, there is evidence to suggest that the nicotine patch is not effective. sufficient insufficientConsider a drug that is used to help prevent blood clots in certain patients. In clinical trials, among 6131 patients treated with this drug, 161 developed the adverse reaction of nausea. Use a 0.05 significance level to test the claim that 3% of users develop nausea. Does nausea appear to be a problematic adverse reaction? Identify the null and alternative hypotheses for this test. Choose the correct answer below. O A. Ho: P = 0.03 H1: p > 0.03 O B. Ho: P = 0.03 Hy: p # 0.03 O C. Ho: p # 0.03 H, : p = 0.03 O D. Ho: P = 0.03 H1: P = 0.03 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 rejection of the claim that 3% of users develop nausea O B. Fail to reject Ho. There is sufficient evidence to warrant rejection of the claim that 3% of users develop nausea. O C. Reject Ho. There is sufficient evidence to warrant rejection of the claim that 3% of users develop nausea. O D. Fail to reject Ho. There is not sufficient evidence to warrant rejection of the claim that 3% of users develop nausea. Does nausea appear to be a problematic adverse reaction? Since the rate of nausea appears to be relatively it a problematic adverse reaction. high is not low, is
