Researchers measured the data speeds for a particular smartphone carrier at 50 airports. The highest speed measured was 74.3 Mbps. Th peeds has a mean of x = 15.94 Mbps and a standard deviation of s = 22.26 Mbps. .What is the difference between carrier's highest data speed and the mean of all 50 data speeds? . How many standard deviations is that [the difference found in part (a)]? . Convert the carrier's highest data speed to a z score. . 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 ignificant?

i believe i think you answer three at a time right? can you please help me solve a,b,c? thank you so much I'm confused

Researchers measured the data speeds for a particular smartphone carrier at 50 airports. The highest speed measured was 74.3 Mbps. The complete list of 50 data speeds has a mean of x = 15.94 Mbps and a standard deviation of s = 22.26 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.)
