For a data set of the pulse rates for a sample of adult​ females, the lowest pulse rate is 33 beats per​ minute, the mean of the listed pulse rates is x=72.0 beats per​ minute, and their standard deviation is s=14.5 beats per minute. a) What is the difference between the pulse rate of 33 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 33 beats per minute to a z score.
