Its hard for smokers to quit. Perhaps prescribing a drug to fight depression will work as well
Question:
It’s hard for smokers to quit. Perhaps prescribing a drug to fight depression will work as well as the usual nicotine patch. Perhaps combining the patch and the drug will work better than either treatment alone. Here are data from a randomized, double-blind trial that compared four treatments. A “success” means that the subject did not smoke for a year following the start of the study.
a. Summarize these data in a two-way table.
b. Do the data provide convincing evidence of a difference in the effectiveness of the four treatments at the α = 0.05 significance level?
