In one study of smokers who tried to quit smoking with nicotine patch therapy, 39 were smoking one year after the treatment, and 32 were not smoking one year after the treatment. Use a 0.10 significance level to test the claim that among the smokers who try to quit with the nicotine patch therapy, the majority are smoking a year after the treatment. Do these results suggest that the nicotine patch therapy is ineffective?

Take a shot, what do you think?
Hint: your question involves a binominal distribution; the formula for the standard deviation is sqrt(n*p*q), where n is the sample size, p it the expected probability, and q=1-p.
Also, you will need a cumulative normal distribution table, probably in the back of your stats text.
