Researchers measured the data speeds for a particular smartphone carrier at 50 airports. The highest speed measured was 76.4 Mbps. The complete list of 50 data speeds has a mean of x= 15.55 Mbps and a standarddeviation of s = 39.83 Mbpsa. 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 (al?c. Convert the carrier's highest data speed to a z scored. 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?

deviation of s = 39.83 Mbps. Researchers measured the data speeds for a particular smartphone carrier at 50 airports. The highest speed measured was 76.4 Mops.

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.) b. The difference is standard deviations. (Round to two decimal places as needed.) c. The z score is z = (Round to two decimal places as needed.) d. The carrier's highest data speed is significantly low. significantly high. not significant. VI Next
