NW 5.10 Consider the following probability distribution: p(x) 33 mean. = 33 N 13 a. Find u. b. For a random sample of n = 3 observations from this distribution, find the sampling distribution of the sample c. Find the sampling distribution of the median of a sample of n = 3 observations from this population. d. Refer to parts b and c, and show that both the mean and median are unbiased estimators of μ for this population. e. Find the variances of the sampling distributions of the sample mean and the sample median. f. Which estimator would you use to estimate μ? Why?
