Sampling distribution of mean questions. For a population of size N, if we take a sample of size n, there are (N n) A normal distribution has a mean of 20 and a standard deviation of 10. . Find the mean and standard deviation of the sample mean. Review key concepts and prepare Because the central limit theorem states that the sampling distribution of the sample means follows a normal distribution (under the right conditions), the normal distribution can be used to answer Explore Quizlet's library of 10 Sampling Distributions Practice Test practice questions made to help you get ready for test day.
