Question

An olympic runner estimates that the probability that she runs the NYC marathon in less that 3.5 hrs is 0.8413 and the probability that she completes it in less that 4.5 hrs is 0.9772. Calculate the probability that she finishes in less that 3 hrs. Assume that the marathon running times are normally distributed.

Answer #1

25 runners and 25 bikers are randomly chosen to do the same
race. The runners took 30 minutes to complete the race on average
and the standard deviation was 5 minutes. The bikers took 35
minutes to complete the race on average and their standard
deviation was 8 minutes. Assume that the race completion times are
normally distributed for both groups.
