Question

Stanford university conducted a study of where the running is healthy for men and women over age 50. During that first eight years of the study, 2.7% of the 774 members of the 50 – plus fitness association died. we were interested in the proportion of people over 50 grand and died in the same eight year.

a) define the random variables X and P' in words.

B) which distribution should you use for this problem?

c) construct a 95% confidence interval for the population proportion of people over 50 who ran and died in the same eight- year period.

enter your answer in interval notation.
round your answer to four decimal places.

d) explain what a 95% confidence interval means for this study
