Assume that females have pulse rates that are normally distributed with a mean of 74.0 beats per minute and a standard deviation of 12.5 beats per minutes. if 16 adult female is randomly selected, find the probability that her pulse rate is less than 80 beats per minute.

0.9726

Step-by-step explanation:

Given :  Females have pulse rates that are normally distributed with a mean of 74.0 beats per minute and a standard deviation of 12.5 beats per minutes.

i.e. and

Let x is a random variable to represent the pulse rates.

Formula :

For n= 16 , the probability that her pulse rate is less than 80 beats per minute will be :-

Hence, the required probability = 0.9726
