Commute distances for employees of a large company have a distribution that is quite skewed. Suppose the mean commute distance is 20 miles and that the standard deviation is 7 miles. What can be said about the mean commute distance for a random sample of size 49 employees from this plant?
A) The distribution of 
will be approximately normal with mean 20 and standard deviation 7.
B) The distribution of 
will be approximately normal with mean 20 and standard deviation 1.
C) The mean and standard deviation of 
will be 20 and 7, but the sampling distribution of 
will not be approximately normal.
D) The mean and standard deviation of 
will be 20 and 1, but the sampling distribution of 
will not be approximately normal.
E) 
will have a standard normal distribution.
