Acertain group of test subjects had pulse rates with a mean of 73.1 beats per minute and a standard deviation of 10.7 beats per minute. use the range rule of thumb to identify the limits separating values that are significantly low or significantly high. is a pulse rate of 84.5 beats per minute significantly low or significantly high

A certain group of test subjects had pulse rates with a mean of 73.1 beats per minute and a standard deviation of 10.7 beats per minute. Use the range rule of thumb to identify the limits separating values that are significantly low or significantly high. Is a pulse rate of 84.5 beats per minute significantly low or significantly high

Solution: We are given:

We have to find the limits that will separate the values that are significantly low or significantly high.

Rule of thumb is:

Lower limit

Upper limit

Therefore, the lower limit

the upper limit

Hence, the limits separating values that are significantly low or significantly high are

Is a pulse rate of 84.5 beats per minute significantly low or significantly high

The pulse rate of 84.5 beats per minute is neither significantly low nor significantly high. The pulse rate of 84.5 beats per minute is usual.
