(7) Given: To calculate the standard deviation, we first need to calculate the variance. To find the variance, we find the squared deviations from the expected return of the investment. We then multiply each possible squared deviation by its probability; we then add all of these up. The result is the variance, the square root of which is the standard deviation. You are doing an investment analysis and have come with the following IRR's, or expected returns: IRR Scenario Recession Normal Boom Probability 30% 50% 20% -2% 14% What is the standard deviation of the return on this investment?
