If the original population is normally​ distributed, then for any sample size​ n, the sample means will be normally distributed. B. If the distribution of the sample means is normally​ distributed, and ngreater than​30, then the population distribution is normally distributed. C. The distribution of sample means gets closer to a normal distribution as the sample size n gets larger. D. If the original population is not normally distributed and ngreater than​30, the distribution of the sample means can be approximated reasonably well by a normal distribution.
