Question
Researchers measured the data speeds for a particular smartphone carrier at 50 airports. The highest speed measured was
72.6
Mbps. The complete list of 50 data speeds has a mean of
x=18.29
Mbps and a standard deviation of
s=19.75
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?Question content area bottom
Part 1
