QuestionNormal distribution: Given expected return rˉ=18.9%\bar{r} = 18.9\% and CV=0.75C V = 0.75, find: a. σr\sigma_{r}, b. ranges for 68%,95%,99%68\%, 95\%, 99\%, c. draw the distribution.

Studdy Solution
The probability distribution associated with these findings can be drawn as a normal distribution curve with mean rˉ\bar{r} and standard deviation σr\sigma_{r}. The ranges calculated above represent the intervals within which the return will fall with 68%68\%, 95%95\%, and 99%99\% probability respectively.
