following are three economic states, their likelihoods, and the potential returns:

  Economic State Probability Return  Fast growth 0.27 34 %  Slow growth 0.35 7   Recession 0.38 -29 

Determine the standard deviation of the expected return. (Do not round intermediate calculations and round your answer to 2 decimal places.)
