find variance and standard deviation of the three investments.

Varlance and standard doviation (expectod). Bacon and Associates, a famous Northwest think tanik, has provided probability ostimales for tho four potential oconomio states for the coming yoar in the following table: . The probability of a boom economy is 22\%, the probability of a stable growth economy is 42%, the probabily of a. stagnant economy is 24%, and the probabiity of a rocession is 12%. Calculate the variance and the standard deviation of the threo investiments: stock, corporate bond, and government bond. If the estimales for both the probabilies of the economy and the returns in each state of the economy are correct, which imvestment would you choose, considering both risk and selurn? Hint: Make sure to round all intermedate calculatons to at least seven (7) decimal places. The inpet instrucfions, phrases in parenthesis after ench answer box, only apply for the answers you will type. What is the varinnce of the stock investment? K. (Round to fivo decirnal places.)
