Researchers measured the data speeds for a particular smartphone
carrier at 50 airports. The highest speed measured was 74.1 Mbps.
The complete list of 50 data speeds has a mean of x=17.59 Mbps and
a standard deviation of s=36.21 Mbps.
a. What is the difference between​ carrier's highest data
speed and the mean of all 50 data​ speeds?
b. How many standard deviations is that​ [the difference
found in part​ (a)]?
c. Convert the​ carrier's highest data speed 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​ carrier's highest data
speed​ significant?
