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). Themean maximum oxygen uptake for elite athletes has been found to be 70 with a standard deviation of 8.6. Assume that the distribution is approximatelynormal. What is the probability that an elite athlete has a maximum oxygen uptake of at least 65 ml/kg? What is the probability that an elite athlete has a maximum oxygen uptake of 70 ml/kg or lower? (c) Consider someone with a maximum oxygen uptake of 36 ml/kg. Is it likely that this person is an elite athlete? Write "YES" or "NO."
