Quit Smoking: The New England Journal of Medicine published the results of a double-blind, placebo-controlled experiment to study the effect of nicotine patches and the antidepressant bupropion on quitting smoking. With the data from the experiment we calculate the sample difference in the "quit smoking" rates for the nicotine treatment group and the placebo group ("treatment" minus "placebo"). We get 0.8% = 0.008. Which of the following is an appropriate conclusion based on this finding?
A) In this experiment the nicotine treatment had a higher success rate than the placebo group, but the improvement was less than 1%.
B) In this experiment, the placebo group had a higher success rate than the nicotine group by 0.8%.
C) Nicotine patches will produce a slightly higher success rate when compared to a placebo, but the difference is not statistically significant.
D) Nicotine patches and the antidepressant bupropion work equally well on "quit smoking" rates.
