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 60.5 with a standard deviation of 7.5. Assume that the distribution is approximately normal. Find the probability that an elite athlete has a maximum oxygen uptake of at least 69.5 ml/kg. Find the probability that an elite athlete has a maximum oxygen uptake of at most 43.25 ml/kg. Find the probability that an elite athlete has a maximum oxygen uptake of 43.25 ml/kg. Submit
