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 = 71.0 beats per
minute, and their standard deviation is s = 22.3 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 data speeds 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?
a. The difference is 34 beats per minute.
(Type an integer or a decimal. Do not round.)
b. The difference is 1.52 standard deviations.
(Round to two decimal places as needed.)
c. The z score is z=-1.52'.
(Round to two decimal places as needed.)
d. The lowest pulse rate is not significant.
