Basic Computation: Central Limit Theorem Suppose has a distribution with a mean of 20 and a standard deviation of 3. Random samples of size n = 36 are drawn. a. Describe the distribution and compute the mean and standard deviation of the distribution. b. Find the z value corresponding to = 19. c. Find P(<19). d. Interpretation Would it be unusual for a random sample of size 36 from the x distribution to have a sample mean less than 19? Explain.
