Normal probability distribution 1.55, answer the foilowing questions answer the Assuming that the rates of return associated with a a. Find the standard deviation of returns,o b. Calculate given asset investment the range of expected return outcomes associated with the following are normally distributed, that the ex a. The standard deviation of retums, o, is (Round to three decimal places.) of occurrence: (1) 68%, (2) 95%, (3) 99%. The highest possbe expected return associated with the 68% probablity of occurrence is we, the 68% protablity of occurr-is%. (Round to two decimal places.) possble expected return associated with the 95% probablity of occurrence is (Round to two decimal places.) %. (Round to two deo mal places.) expected return associated wit, the 96% probability of occurrence (3) The lowest possible expected return associated with the 99% i % (Round to two dermal places ) probability of occurrence ability of our ence is The highest possible expected return associated with the 99% pro %.
