Researchers measured the data speeds for a particular smartphone carrier at 50 airports. The highest speed measured was 75.5 Mbps. 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? p. 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? - The difference is Mbps. Type an integer or a decimal. Do not round.)

Question
Researchers measured the data speeds for a particular smartphone carrier at 50 airports. The highest speed measured was 75.5 Mbps. 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 the carrier's highest data speed significant? a. The difference is Mbps. (Type an integer or a decimal. Do not round.)
