Normal probability distributionAssuming that the rates of return associated with a given asset investment are normally distributed; that the expected return,

r,

is

15.9%;

and that the coefficient of variation,

CV,

is

0.55,

answer the following questions:a.Find the standard deviation of returns,

r.

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,

r,

is

nothing%.

(Round to three decimal places.)b. (1) The lowest possible expected return associated with the 68% probability of occurrence is

nothing%.

(Round to two decimal places.)The highest possible expected return associated with the 68% probability of occurrence is

nothing%.

(Round to two decimal places.)(2) The lowest possible expected return associated with the 95% probability of occurrence is

nothing%.

(Round to two decimal places.)The highest possible expected return associated with the 95% probability of occurrence is

nothing%.

(Round to two decimal places.)(3) The lowest possible expected return associated with the 99% probability of occurrence is

nothing%.

(Round to two decimal places.)The highest possible expected return associated with the 99% probability of occurrence is

nothing%.

(Round to two decimal places.)
