For a data set of the pulse rates for a sample of adult​ females, the lowest pulse rate is

beats per​ minute, the mean of the listed pulse rates is

beats per​ minute, and their standard deviation is

beats per minute.

a. What is the difference between the pulse rate of

beats per minute and the mean pulse rate of the​ females?

b. How many standard deviations is that​ [the difference found in part​ (a)]?

c. Convert the pulse rate of

beats per minutes to a z score.

d. If we consider pulse rates that convert to z scores between

and 2 to be neither significantly low nor significantly​ high, is the pulse rate of

beats per minute​ significant?
