Distribution Skew of Airplane Taxi Waits

For air travelers, one of the biggest complaints is of the waiting time between when the airplane taxis away from the terminal until the flight takes off. This waiting time is known to have a skewed-right distribution with a meanof 10 minutes and a standard deviationof 8 minutes. Suppose 100 flights have been randomly sampled. Describe the samplingdistribution of the mean waiting time between when the airplane taxis away from the terminal until the flight takes off for these 100 flights.

A. Distribution is skewed-right with mean = 10 minutes and standard error= 0.8 minutes
B. Distribution is skewed-right with mean = 10 minutes and standard error = 8 minutes
C. Distribution is approximately normal with mean = 10 minutes and standard error = 0.8 minutes
D. Distribution is approximately normal with mean = 10 minutes and standard eror = 8 minutes

Solution briefly works out the standard error in order to find the distribution’s skewing.
