Question: Consider the following probability distribution: a. Find . b. For a random sample of n = 3 observations from this distribution, find the sampling distribution

Consider the following probability distribution:

P(x) 2


a. Find μ.

b. For a random sample of n = 3 observations from this distribution, find the sampling distribution of the sample mean.

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?
