in the last quarter of 2007, a group of 64 mutual funds had a mean return of 4.3 % with a standard deviation of 7.2%. 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 -2.9% or less c) Returns between - 10.1% and 18.7% b) Returns of 4.3% or less d) Returns of less than - 17.3% a) The expected percentage of returns that are -2.9% or less is (Type an integer or a decimal.) b) The expected percentage of returns that are 4.3% or less is (Type an integer or a decimal.) c) The expected percentage of returns that are between -10.1% and 18.7% is% (Type an integer or a decimal.) d) The expected percentage of returns that are-17.3% or less is% (Type an integer or a decimal.) in the last quarter of 2007, a group of 64 mutual funds had a mean return of 4.3 % with a standard deviation of 7.2%.
