Question

In one study of smokers who tried to quit smoking with nicotine patch​ therapy, 39 were smoking one year after treatment and 32 were not smoking one year after the treatment. Use a 0.10 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. 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 Identify the test statistic for this hypothesis test. ​(Round to two decimal places as​ needed.) Identify the​ P-value for this hypothesis test. ​(Round to three decimal places as​ needed.) Identify the conclusion for this hypothesis test. A. Fail to reject H0. There insufficient evidence to warrant support of the claim that the majority are smoking one year after the treatment. B. Reject H0. There insufficient evidence to warrant support of the claim that the majority are smoking one year after the treatment. C. Reject H0. There sufficient evidence to warrant support of the claim that the majority are smoking one year after the treatment. D. Fail to reject H0. 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 ▼ sufficient or insufficient evidence to support the claim that the majority are smoking one year after the​ treatment, there is ▼ insufficient or sufficient evidence to suggest that the nicotine patch is not effective.
