Question

the pulse rate adult men approach a normal distribution, ith a mean 80bpm(beats per minute) and a standard deviation of 5 bpm. what percent of adults have a pulse rate of more than 92 bpm?

Answer 1

Use the Laplace function and the table of its values

$P(X>92)=\Phi(\inf)-\Phi(\frac{92-80}{5})\approx0.0082$
