Researchers measured the data speeds for a particular smartphone carrier at 50 airports. The highest speed measured was 75.5Mbps. The complete list of 50 data speeds has a mean of x = 15.67 Mbps and a standard deviation of s = 36.33 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 thecarrier's highest data speed significant?a. The difference is Mbps.(Type an integer or a decimal. Do not round.)

Solution: Given information: n= 50 data speeds Highest data speeds= 75.5 x= 15.67 Sample mean s=…
