Question
For a data set of the pulse rates for a sample of adult females, the lowest pulse rate is
36
beats per minute, the mean of the listed pulse rates is
x=72.0
beats per minute, and their standard deviation is
s=21.9
beats per minute.a. What is the difference between the pulse rate of
36
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
36
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
36
beats per minute significant?a. The difference is
________
beats per minute.(Type an integer or a decimal. Do not round.)
b. The difference is
________
standard deviations.(Round to two decimal places as needed.)
c. The z score is
z=_______
(Round to two decimal places as needed.)
d. The lowest pulse rate is
(1)
(1)
significantly high.
significantly low.
not significant.
