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 1179293: 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 61.5 with a standard deviation of 7.6. Assume that the distribution is approximately normal.
Find the probability that an elite athlete has a maximum oxygen uptake of at least 74.4 ml/kg.
Find the probability that an elite athlete has a maximum oxygen uptake of at most 41 ml/kg.

Hi
Distribution: normal with µ = 61.5 and σ = 7.6
Find the probability that an elite athlete has:
Continuous Curve
Using TI or similarly an inexpensive calculator like an Casio fx-115 ES plus

P( x ≥  74.4) = normalcdf(74.4, 9999,61.5,7.6) = .0448  
P( x ≤ 41) =  normalcdf(-9999,41,61.5,7.6) = .0035
Wish You the Best in your Studies.
