A study examined a simple random sample of smokers who tried to quit smoking by using either a nicotine patch or e-cigarettes. Here is a quote from a news article referencing the study: "Quitting is hard. The number of people who quit (within 6 months) was low overall-just 38 of the 584 smokers given the e-cigarette or the patch." What is the margin of error for a plus four 95% confidence interval for the true population proportion of smokers who quit within 6 months using either e-cigarettes or the nicotine patch?
