Question: Consider the following discrete probability distribution: x 1 2 3 4 5 p(x)0.1 0.2 0.2 0.3 0.2 Find = E(x) & = E [(x -

Consider the following discrete probability distribution:

x 1 2 3 4 5

p(x)0.1 0.2 0.2 0.3 0.2

Find = E(x) & = E [(x - )2].

Find the probability that the value of x falls within one standard deviation of the

mean. Compare this result to the Empirical Rule.
