Normal probability distribution Assuming that the rates of return associated with a given asset investment are normally distributed; that the expected return, r, is 12.7%; and that the coefficient of variation, CV, is 1.03, answer the following questions: a. Find the standard deviation of returns, a 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, nis %. (Round to three decimal places.) b 1) The lowest possible expected return associated with he 68% probability o occurrence is 9 Round to two decimal places. The highest possible expected return associated with the 68% probability of occurrence is %. (Round to two decimal places.) (2) The lowest possible expected return associated with the 95% probability of occurrence is %. (Round to two decimal places.) The highest possible expected return associated with the 95% probability of occurrence is %. (Round to two decimal places.) (3) The lowest possible expected return associated with the 99% probability of occurrence is %. (Round to two decimal places.) The highest possible expected return associated with the 99% probability of occurren eis %. Round to two decimal places
