You are considering investing in a project with the following possible outcomes: Probability of Investment States Occurrence Returns State 1: Economic boom 20% 16% State 2: Economic growth 40% 12% State 3: Economic decline 20% 5% State 4: Depression 20% -5% Calculate the standard deviation of returns for this investment. Round to the nearset hundredth percent. Answer in the percent format. Do not include % sign in your answer (i. e. If your answer is 4.33%, type 4.33 without a % sign at the end.)

SD = 0.0740270 or 7.40270 percent rounded off to 7.403 percent

Explanation:

To calculate the standard deviation of the investment, we must first calculate the expected or mean return of the investment. The expected or mean return can be calculated as follows,

r = pA * rA  +  pB * rB  +  ...  +  pN * rN

Where,

r = 0.2 * 0.16  +  0.4 * 0.12  +  0.2 * 0.05  +  0.2 * -0.05

r = 0.08 or 8%

The formula to calculate the standard deviation of a stock/investment is as follows,

SD = √pA * (rA - r)²  +  pB * (rB - r)²  +  ...  +  pN * (rN - r)²

SD = √0.2 * (0.16 - 0.08)²  +  0.4 * (0.12 - 0.08)²  +  0.2 * (0.05 - 0.08)²  +  0.2 * (-0.05 - 0.08)²

SD = 0.0740270 or 7.40270 percent rounded off to 7.403 percent

the correct answer is economics is a game without winners or losers.

unlike sports or games economic is a game without losers or winner rather it is a game where everyone wins. parties of business doing businesses exchange money with each other and hence exchange is done on the basis of goods. one party takes the goods and other sales it so there is winner on both sides. each party values more highly the good it gets than the good it gives up. both sides exchange only because both intend to increase their value. so there is no concept of lose or win.
