Researchers measured the data speeds for a particular smartphone carrier at 50 airports. The highest speed measured was 75.8 Mbps. Mbps. The complete list of 50 data speeds has a mean of x=15.78 Mbps and a standard deviation of s=38.04 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? a. The difference is ________? Mbps.
