Suppose you want to eat lunch at a popular restaurant. the restaurant does not take reservations, so there is usually a waiting time before you can be seated. let x represent the length of time waiting to be seated. from past experience, you know that the mean waiting time is
μ = 17.8 minutes with σ = 4.3 minutes. you assume that the x distribution is approximately normal. (round your answers to four decimal places.)
(a) what is the probability that the waiting time will exceed 20 minutes, given that it has exceeded 15 minutes? hint: compute p(x > 20|x > 15).
(b) what is the probability that the waiting time will exceed 25 minutes, given that it has exceeded 18 minutes?

Suppose that 3% of all athletes are using the endurance-enhancing hormone epo (you should be able to simply compute the percentage of all athletes that are not using epo). for our purposes, a “positive” test result is one that indicates presence of epo in an athlete’s bloodstream. the probability of a positive result, given the presence of epo is .99. the probability of a negative result, when epo is not present, is .90. what is the probability that a randomly selected athlete tests positive for epo? 0.0297
