Researchers measured the data speeds for a particular smartphone carrier at 50 airports. The highest speed measured was a 78.5 Mbps. The complete list of 50 data speeds has a mean of x=17.93 Mbps and a standard deviation of s=32.49 Mbps. A). What is the difference between carrier's highest data speed and the mean of all 50 data speeds? B). How many standard deviation 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 a z scores between -2 and 2 to be neither significantly low nor significantly high, is the carrier's highest data speed significant
