SOLUTION: 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

Question 1126909: 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 8.6. Assume that the distribution is approximately normal.
A.) What is the probability that an elite athlete has a maximum oxygen uptake of at least 65 ml/kg?
B.) What is the probability that an elite athlete has a maximum oxygen uptake of 55 ml/kg or lower?
C.) Consider someone with a maximum oxygen uptake of 37 ml/kg. Is it likely that this person is an elite athlete? Write "YES" or "NO."

z=(x-meaqn)/sd
A. z >= -5/8.6 or -0.58. Probability z > than that is 0.7190
B. z< -15/8.6 or < -1.74. Probability is 0.0409
C. NO. It is far, far to the left of the curve and is not at all likely
