\fa. Find p. (Round to two decimal places as needed.) b. For a random sample of n = 3 observations from this distribution, find the sampling distribution of the sample mean. Type the answers in ascending order for x. (Type Integers or simplified fractions.) c. Find the sampling distribution of the median, M. of a sample of n = 3 abservations from this population. Type the answers in ascending order for M. p(M [Type Integers or simplified fractions.) d. Refer to parts b and c, and determine if the mean and median are unbiased estimators of a for this population. Chance the correct answer below. O A. Both the sample mean, x, and the sample median, M, are unbiased estimators because their distributions have a mean equal to the population mean. O B. Both the sample mean, x, and the sample median, M, are biased estimators because their distributions can produce values olher than the population mean. O C. Only the sample median. M, is unbiased because its distribution has a mean equal to the population mean. O D. Both the sample mean, x, and the sample median. M. are biased estimators because their distributions have means equal to the population mean. O E. Only the sample mean, x, is unbiased because its distribution has a mean equal to the population mean. e. Find the variances of the sampling distributions of the sample mean and the sample median
