A population is skewed strongly to the right with a mean of 140 and a standard deviation of 18. We create a sampling distribution of the means of samples of size 8. Which of the following statements are correct?
A. The mean of the sampling distribution is 140 and the standard deviation is 6.36.
B. The mean of the sampling distribution is 140, but there isn't enough information to determine the standard deviation.
C. The mean of the sampling distribution is 140 and the standard deviation is 2.25.
D. The mean of the sampling distribution is 140 and the standard deviation is 18.
E. Because the distribution is skewed to the right, the standard, deviation of the sampling distribution can't be determined.
B. The mean of the sampling distribution is 140, but there isn't enough information to determine the standard deviation.
E. Because the distribution is skewed to the right, the standard deviation of the sampling distribution can't be determined.
