\a) is there evidence yo show a difference in the proportion of activity for the 60-64 age group by gender?

b) construct a 95% confidence interval for the difference in proportion of men and women that excursive at least once a week.

A health study tracked a group of persons for five years. At the beginning of the study, 25% were classified as heavy smokers, 35% as light smokers, and 40% as nonsmokers. Results of the study showed that light smokers were twice as likely as nonsmokers to die during the five-year study, but only half as likely as heavy smokers. A randomly selected participant from the study died over the five-year period. Compute the probability that the participant was a nonsmoker.
