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." Are the conditions for this inference procedure met?

The study was a simple random sample, and the sample size is large enough (n = 584) to use the normal distribution to approximate the binomial distribution. The number of successes (38) is also large enough (np = 38 > 10 and n(1-p) = 546 > 10) to use the normal distribution to approximate the binomial distribution.
