SOLUTION: Assume that females have pulse rates that are normally distributed with a mean of mu equals 76.0 beats per minute and a standard deviation of sigma equals 12.5 beats per minute. Co

Question 1147820: Assume that females have pulse rates that are normally distributed with a mean of mu equals 76.0 beats per minute and a standard deviation of sigma equals 12.5 beats per minute. Complete parts (a) through (c) below.
a. If 1 adult female is randomly selected, find the probability that her pulse rate is less than 82 beats per minute.
The probability is...

Z-score = = = = 0.48

Go to a z-table and look up +0.48. At a z-score of +0.48, the area to the left of the curve is 0.6844.

So, the probability is 0.6844 that her pulse rate is less than 82 beats per minute.
