Question

a. For a certain group of individuals, the average heart rate is 70 beats per minute. Assume the variable is normally distributed and the standard deviation is 3 beats per minute. If a subject is selected at random, find the probability that the person has the following heart rate. Round the final answers to at least four decimal places and intermediate z-value calculations to two decimal places.Less than 74 beats per minute

Answer 1

We were given the following information:

Average heart rate = 70 beats per minute

The variable is normally distributed

Standard deviation = 3 beats per minute

The probability that someone chosen at random has less than 74 beats per minute is obtained as shown below:
