Researchers measured the data speeds for a particular smartphone carrier at 50 airports . The highest speed measured was 75. 7 Mops . The complete list of 50 data speeds has a mean of * = 16. 67 Mops and a standard deviation of s = 35.47 Mops . 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
