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 70 with a standard deviation of 9.8. Assume that the distribution is approximately normal. (a) What is the probability that an elite athlete has a maximum oxygen uptake of at least 70 ml/kg? 0.5 (b) What is the probability that an elite athlete has a maximum oxygen uptake of 65 ml/kg or lower? (c) Consider someone with a maximum oxygen uptake of 38 ml/kg. Is it likely that this person is an elite athlete? Write "YES" or "NO."
