Suppose that a category of world class runners are known to run a marathon (26 miles) in an average of l47 minutes with a standard deviation of l12 minutes. Consider 49 of the races. Let X= the average of the 49 races. Find the probability that the average of the sample will be between 144 and 148 minutes in these 49 marathons. (Round your answer to four decimal places.) Find the median of the average running times.

Researchers measured the data speeds for a particular smartphone carrier at 50 airports. The highest speed measured was 77.977.9 Mbps. The complete list of 50 data speeds has a mean of x overbarxequals=17.5417.54 Mbps and a standard deviation of sequals=18.9718.97 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 minus−2 and 2 to be neither significantly low nor significantly high, is the carrier's highest data speed significant?
