A study reported in Newsweek (December 23, 1991) involved a sample of 931 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 250 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.)
