StatisticsQ&A LibraryFor a data set of the pulse rates for a sample of adult females, the lowest pulse rate is 39 beats per minute, the mean of the listed pulse rates is x overbar equals 77.0 beats per minute, and their standard deviation is sequals 21.2 beats per minute. a. What is the difference between the pulse rate of39 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 of39 beats per minutes to a z score. d. If we consider data speeds that convert to z scores between minus 2 and 2 to be neither significantly low nor significantly high, is the pulse rate of 39 beats per minute significant?Question

For a data set of the pulse rates for a sample of adult females, the lowest pulse rate is 39 beats per minute, the mean of the listed pulse rates is x overbar equals 77.0 beats per minute, and their standard deviation is sequals 21.2 beats per minute.

a. What is the difference between the pulse rate of39 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 of39 beats per minutes to a z score.

d. If we consider data speeds that convert to z scores between minus 2 and 2 to be neither significantly low nor significantly high, is the pulse rate of 39 beats per minute significant?
