Question
For a data set of the pulse rates for a sample of adult​ females, the lowest pulse rate is
3838
beats per​ minute, the mean of the listed pulse rates is
x overbarxequals=77.077.0
beats per​ minute, and their standard deviation is
sequals=22.322.3
beats per minute.
 
a. What is the difference between the pulse rate of
3838
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
3838
beats per minutes to a z score.
d. If we consider pulse rates that convert to z scores between
minus−2
and 2 to be neither significantly low nor significantly​ high, is the pulse rate of
3838
beats per minute​ significant?
a. The difference is
3939
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.)
 
Can someone help I'm stuck on fiquiring out part b?
