The random variable W can take on the values of 0, 1, 2, 3, or 4. The expected value of W is 2.8. Which of the following is the best interpretation of the expected value of random variable W?

A. A randomly selected value of W must be equal to 2.8.

B.The values of W vary by about 2.8 units from the mean of the distribution.

C.The mean of a random sample of values selected from the distribution will be 2.8.

D.A value of W randomly selected from the distribution will be less than 2.8 units of the mean.

E. For values of W, repeatedly selected at random from the distribution, the mean of the selected values will approach 2.8.
