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 right skewed distribution with a mean of 10 minutes and a standard deviation of 8 minutes. Suppose 100 flights have been randomly sampled. Describe the sampling distribution 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 right skewed with mean = 10 minutes and standard error = 0.8 minutes.
B) Distribution is approximately normal with mean = 10 minutes and standard error = 0.8 minutes.
C) Distribution is approximately normal with mean = 10 minutes and standard error = 8 minutes.
D) Distribution is right skewed with mean = 10 minutes and standard error = 8 minutes.
