Normal probability distribution Assuming that the rates of return associated with a given asset investment are normally distributed; that the expected return, r, is 15.7%; and that the coefficient of variation, CV, is 0.84, answer the following questions: a. Find the standard deviation of returns, Or: b. Calculate the range of expected return outcomes associated with the following probabilities of occurrence: (1) 68%, (2) 95%, (3) 99%. a. The standard deviation of returns, Or, is 13.188 %. (Round to three decimal places.) b. (1) The lowest possible expected return associated with the 68% probability of occurrence is %.
