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 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
с
The mean of a random sample of values selected from the distribution will be 2.8
D
A value of randomly selected from the distribution will be less than 2.8 units of the mean
E
For values of Wrepeatedly selected at random from the distribution the mean of the selected values will approach 2.8.
