The phonysoical fitness of an athlete is often measured by how much oxygen the athlete takes in (which isrecorded in milliliters per kilogram, ml/kg). The mean maximum oxygen uptake for elite athletes has beenfound to be 62.5 with a standard deviation of 7.9. Assume that the distribution is approximately normal.Find the probability that an elite athlete has a maximum oxygen uptake of at least 79.1 ml/kg.Find the probability that an elite athlete has a maximum oxygen uptake of at most 52.2 ml/kg.Submit QuestionFor the Grouped Frequency Distribution Tables, when it says a "nice" class width, the class width will alwaysbe one of the following values:.1, .2, .25, .5,1, 2, 2.5, 5,10, 20, 25, 50,100, 200, 250, 500,1000, 2000, 2500, 5000,10000, 20000, 25000, 50000Q Search
