In one study of smokers who tried to quit smoking with nicotine patch therapy, 37 were smoking one year after treatment and 30 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

H0: p > 0.5 H1: p = 0.5 Identify the test statistic for this hypothesis test. The test statistic for this hypothesis test is 0.35. (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.)

A study of 250 randomly selected smokers who tried to quit smoking with nicotine patch therapy is conducted. After the study, it is found that 60% are still smoking a year later. Use a 5% significance to test the statement that among smokers who try to quit with nicotine patch therapy, less than 75% are still smoking a year later. Please include your requirements, null and alternative hypotheses, test statistic (show equation), p-value, decision rule and conclusion.
