A study reported in Newsweek (December 23, 1991) involved a
sample of 940 smokers. Each individual received a nicotine patch,
which delivers nicotine to the bloodstream but at a much slower
rate than cigarettes do. Dosage was decreased to 0 over a 12-week
period. Suppose that 245 of the subjects were still not smoking 6
months after treatment (this figure is consistent with information
given in the article). Estimate the proportion of all smokers who,
when given this treatment, would refrain from smoking for at least
6 months. (Give the answer to three decimal places.)

Suppose that 905 smokers each
received a nicotine patch, which delivers nicotine to the
bloodstream at a much slower rate than cigarettes do. Dosage was

still not smoking 6 months after treatment. Assume this sample is
representative of all smokers.
