Refer to Exercise 6.5 and find E(x) = (. Then use the sampling distribution of xÌ… found in Exercise 6.5 to find the expected value of xÌ… . Note that E(x) = (?

Refer to exercise 6.5,

Consider the population described by the probability distribution shown here:

The random variable x is observed twice. If these observations are independent, verify that the different samples of size 2 and their probabilities are as follows:
