In the last quarter of 2007, a group of 64 mutual funds had a mean return of 2.8% with a standard deviation of 6.5% 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 -16.7% or less c) Returns...
