The distribution of the commute times for the employees at a large company has mean 22.4 minutes and standard deviation 6.8 minutes. A random sample of n employees will be selected and their commute times will be recorded. What is true about the sampling distribution of the sample mean as n increases from 2 to 10 ? The mean increases, and the variance increases. A The mean increases, and the variance decreases.
B The mean does not change, and the variance does not change.
C The mean does not change, and the variance increases.
D The mean does not change, and the variance decreases.
