Jason would like to invest in gold and is aware that the returns on such an investment can be quite volatile. Use the following table of states, probabilities, and returns to determine the coefficient of variation for the investment. (Round answer to 5 decimal places, e.g. 0.07680.) Probability Return Boom 0.1 35% Good 0.2 19% Ok 0.3 7% Level 0.2 2% Slump 0.2 -32%

Coefficient of Variation

(I keep getting 5.87617... if someone could show me the math so that I know where I am going wrong).

Thanks!
