In one study of smokers who tried to quit smoking with nicotine patch therapy, 37 were smoking one year after treatment and 35 were not smoking one year after the treatment. Use a 0.01 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. Upper H 0: pequals0.5 Upper H 1: pgreater than0.5 B. Upper H 0: pequals0.5 Upper H 1: pless than0.5 C. Upper H 0: pgreater than0.5 Upper H 1: pequals0.5 D. Upper H 0: pequals0.5

Suppose that 905 smokers each
received a nicotine patch, which delivers nicotine to the
bloodstream at a much slower rate than cigarettes do. Dosage was
decreased to 0 over a 12 week period. Of these 905 people, 255 were
still not smoking 6 months after treatment. Assume this sample is
representative of all smokers.
