Problem:
A variety of routine maintenance checks are made on commercial airplanes prior to each takeoff. A particular maintenance check of an airplane's landing gear requires an average of 13 minutes of a maintenance engineer's time. In fact, the exact time required is normally distributed with a mean of 13 minutes and a standard deviation of 4 minutes. As part of a larger simulation model designed to determine total on-ground maintenance time for an airplane, we will need to simulate the actual time required to perform this maintenance check on the airplane's landing gear.
Required:
Question: Using random numbers of 0.1547, 0.9435, 0.3171, 0.5105, and 0.7237, compute the time required for each of five simulated maintenance checks of the airplane's landing gear.
Note: Provide support for your underlying principle.
If required, round your answers to two decimal places.
