P8-18 (similar to) Question Help O Variance and standard deviation (expected). Bacon and Associates, a farrous Northwest think tank, has provided probability estimates for the four potential economic states for the coming year in the following table: E. The probability of a boom economy is 20%, the probability of a stable growth economy is 43%, the probability of a stagnant economy is 21%, and the probability of a recession is 16%. Calculate the variance and the standard deviation of the three investments: stock, corporate bond, and government bond. If the estimates for both the probabilities of the economy and the retumis in each state of the economy are correct, which investment would you choose, considering both risk and return?
