Problem

Researchers measured the data speeds for a particular smartphone carrier at 50 airports. The highest speed measured was 73.5 Mbps. The complete list of 50 data-speeds has a mean of x¯=17.37Mbps and a standard deviation of s=17.33Mbps.
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.
a. The difference is Mbps.
(Type an integer or a decimal. Do not round.)

Answer

Final Answer: The difference between the carrier's highest data speed and the mean of all 50 data speeds is 56.13 Mbps.

Steps

Step 1 :Given that the highest data speed is 73.5 Mbps and the mean of all 50 data speeds is 17.37 Mbps.

Step 2 :Calculate the difference between the highest data speed and the mean of all 50 data speeds by subtracting the mean from the highest data speed: 73.517.37=56.13 Mbps.

Step 3 :Final Answer: The difference between the carrier's highest data speed and the mean of all 50 data speeds is 56.13 Mbps.
