At least one of the answers above is NOT correct.
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 with a standard deviation of 7.9. Assume that the distribution is
approximately normal.
(a) What is the probability that an elite athlete has a maximum oxygen uptake of at least 55 ml/kg?
answer: 0.758
(b) What is the probability that an elite athlete has a maximum oxygen uptake of 60 ml/kg or lower?
answer:
0.5
(c) Consider someone with a maximum oxygen uptake of 28 ml/kg. Is it likely that this person is an elite athlete? Write "YES" or "NO."
answer:
No
Calculate your z-scores to at least 3 decimal places when finding the probability, to insure that rounding is not an issue.
