Suppose that pulse rates among healthy adults are normally distributed with a mean of 81 beats/second and a standard deviation of 10 beats/second. What proportion of healthy adults have pulse rates that are more than 94 beats/sec? Round your answer to at least four decimal places.© BrainMass Inc. brainmass.com June 3, 2020, 8:21 pm ad1c9bdddf
Denote by X the pulse rates among healthy adults. Obviously, X is a random variable following a normal distribution with a mean of of 81 beats/second and a standard deviation of 10 ...
This solution shows how to find the proportion of pulse rate above 94 beats/sec.
