Multiple Choice

The probability distribution shown below describes a population of measurements. $$\begin{array} { c | c c c } x & 0 & 2 & 4 \\\hline p ( x ) & 1 / 3 & 1 / 3 & 1 / 3\end{array}$$ Suppose that we took repeated random samples of n = 2 observations from the population described above. Find the expected value of the sampling distribution of the sample mean.

A) 3
B) 1
C) 4
D) 2
