Researchers measured the data speeds for a particular smartphone carrier at 50 airports. The highest speed measured was 73.6 Mbps. The complete list of 50 data speeds has a mean of x=17.91 Mbps and a standard deviation of s=31.89 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 nothing Mbps. (Type an integer or a decimal. Do not round.) b. The difference is nothing standard deviations. (Round to two decimal places as needed.) c. The z score is z=nothing. (Round to two decimal places as needed.) d. The carrier's highest data speed is
