6. Basic Computation: Central Limit Theorem Suppose x 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 a distribution and compute the mean and standard deviation of the distribution. (b) Find the z value corresponding to x 19. (c) Find Pr < 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.
