For a data set of the pulse rates for a sample of adult​ females, the lowest pulse rate is 37 beats per​ minute, the mean of the listed pulse rates is x=73.0 beats per​ minute, and their standard deviation is s=20.5 beats per minute. a. What is the difference between the pulse rate of 37 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 37 beats per minutes to a z score. d. If we consider pulse rates that convert to z scores between −2 and 2 to be neither significantly low nor significantly​ high, is the pulse rate of 37 beats per minute​ significant?
