Question

Use the following list of resting pulse rates of 55 people. The mean of these rates is 73.5, and the standard deviation is approximately 13.2.
 
50, 51, 51, 53, 53, 53, 55, 56, 56, 57, 58, 58, 59, 59, 60
60, 60, 60, 62, 62, 64, 65, 65, 65, 68, 68, 69, 71, 71, 72
72, 73, 75, 76, 77, 78, 78, 81, 81, 81, 82, 82, 82, 82, 83
85, 85, 85, 88, 88, 90, 90, 91, 91, 92
 

Part 1 out of 2
 
a. Determine the pulse rates that are within 1 standard deviation of the mean. What percentage of the total to the nearest 0.1 percent do these rates represent?

Answer 1

Hi Ashii...from Irving, TX...hope you had a great day at school.

Okay...my first question is...do you know how to calculate the mean of a set of values?

Do you know how to find the Standard deviation of the set of numbers?

Then you will need to make sure you understand how to calculate the percentage of these values.

If you are lost, ask for help...not for someone to give you the answer. I can help you...but as a teacher I won't do the problem or give you the answer.
