Question

In the last quarter of 2007, a group of 64 mutual funds had a mean return of 2.7% with a standard deviation of 7.6%. If a normal model can be used to model them, what percent of the funds would you expect to be in each region? Use the 68-95-99.7 rule to approximate the probabilities rather than using technology to find the values more precisely. Be sure to draw a picture first. a) Returns of-12.5% or less b) Returns of 2.7% or more d) Returns of more than 10.3% c) Returns between-20.1% and 25.5%
