Data from the Research and Innovation Technology Administration at the Bureau of Transportation statistics includes information for every flight to and from the George Bush International Airport (IAH) during the year 2011. The variable TaxiOut records the number of minutes a flight spends taxiing from the gate to the time it lifts off. The mean value of TaxiOut for all flights is 16.9 minutes, with a standard deviation of 7.65 minutes. The histogram for the variable is skewed to the right.

24. If an analyst takes a simple random sample of 50 flights, which of the following statements are true about the sampling distribution for the sample mean of the variable TaxiOut?

A. The shape of the sampling distribution will follow a t-distribution.

B. The shape of the sampling distribution will be approximately normal.

C. The shape of the sampling distribution will follow a 2-distribution.

D. The shape of the sampling distribution will be skewed to the right.
