Based on the following information, calculate the expected return, variance and standard deviation:

State of the Economy	Probability	Rate of Return
Depression	5%	-5.0%
Recession	10%	4.0%
Normal	60%	8.0%
Boom	25%	12.0%

							Adj.		Ret. Dev.
State	Prob.	Stock A		Stock A	Probability	Return	Ret.	Ret. Dev.	Squared	Variance
Depression				Depression
Recession				Recession
Normal				Normal
Boom				Boom
