K Researchers measured the data speeds for a particular smartphone carrier at 50 airports The highest speed measured was 77 4 Mbps The complete list of 50 data speeds has a mean of Mbps and a standard deviation of s 40 19 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 BY
