Which of the following is not a commonly used practice? Choose the correct answer below. O A. The distribution of sample means gets closer to a normal distribution as the sample size n gets larger. O B. If the distribution of the sample means is normally distributed, and n > 30, then the population distribution is normally distributed. O C. If the original population is not normally distributed and n > 30, the distribution of the sample means can be approximated reasonably well by a normal distribution. O D. If the original population is normally distributed, then for any sample size n, the sample means will be normally distributed
