Why does the sampling distribution of the mean follow a normal distribution for a large enough sample​ size, even though the population may not be normally​ distributed?
A. As the sample size gets large​ enough, the sampling distribution of the mean is approximately normally distributed.
B. The sampling distribution of the mean is normally distributed for all sample sizes.
C. As long as the distribution is approximately normally​ distributed, the sampling distribution of the mean is normally distributed for any sample size.
D. As the sample size becomes large enough for a distribution that does not have any​ outliers, the sampling distribution of the mean is normally distributed.
