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 carriers 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 carier's highest data speed significant? a. The difference is Mbps (Type an integer or a decimal. Do not round ) 3 parts
