The physical fitness of an athlete is often measured by how much oxygen the athlete takes in (which is recorded in milliliters per kilogram, ml/kg). The mean maximum oxygen uptake for elite athletes has been found to be 69 with a standard deviation of 7.8. Assume that the distribution is approximately normal. a) Find the probability that an elite athlete has a maximum oxygen uptake of at least 90.8 ml/kg.

Question
The physical fitness of an athlete is often measured by how much oxygen the athlete
takes in (which is recorded in milliliters per kilogram, ml/kg). The mean maximum
oxygen uptake for elite athletes has been found to be 69 with a standard deviation of
7.8. Assume that the distribution is approximately normal. a) Find the probability that
an elite athlete has a maximum oxygen uptake of at least 90.8 ml/kg.
b) Find the probability that an elite athlete has a maximum oxygen uptake of at most
58.9 ml/kg.
