Consider the following information:

				Rate of Return If State Occurs
State of	Probability of
Economy	State of Economy			Stock A			Stock B
Recession		.16			.05			.16
Normal		.62			.08			.13
Boom		.22			.13			.30

Calculate the expected return for each stock. (Do not round intermediate calculations. Enter your answers as a percent rounded to 2 decimal places, e.g., 32.16.)

	Expected return
Stock A	8.62 %
Stock B	12.10 %

Calculate the standard deviation for each stock. (Do not round intermediate calculations. Enter your answers as a percent rounded to 2 decimal places, e.g., 32.16.)

	Standard deviation
Stock A	%
Stock B	%

I only need the standard deviations here for stock A and stock B
