Poisson Distribution · Exercise 23
Approximately 8% of students at a local high school participate in after-school sports all four years of high school. A group of 60 seniors is randomly chosen. Of interest is the number that participated in after-school sports all four years of high school.
(a) In words, define the random variable X.
(b) List the values that X may take on.
(c) How many seniors are expected to have participated in after-school sports all four years of high school?
(d) Based on numerical values, would you be surprised if none of the seniors participated in after-school sports all four years of high school? Justify your answer numerically.
(e) Based on numerical values, is it more likely that four or that five of the seniors participated in after-school sports all four years of high school? Justify your answer numerically.
