A university conducted a study of whether running is healthy for men and women over age 50. During the first eight years of the
study, 1.9% of the 457 members of a fitness association died. We are interested in the proportion of people over 50 who ran and died in the same eight-year period. NOTE: If you are using a Student's t-distribution, you may assume that the underlying population is normally distributed. (In general, you must first prove that assumption, though.)
Define the Random Variables X and P', in words. which of the following?
a.) X is the proportion of people who ran and died in the eight-year period, and P' is the number of people who ran and died in the eight-year period.
b.) X is the proportion of all runners that die, and P' is the number of all runners that die.
c.) X is the number of people who ran and died in the eight-year period, and P' is the proportion of people who ran and died in the eight-year period.
d.) X is the number of all runners that die, and P' is the proportion of all runners that die.
