1. Suppose the returns of a particular group of mutual funds are normally distributed with a mean of 9.7% and a standard deviation of 3.8%. If the manager of a particular fund wants to be sure that his fund is NOT in the bottom 25% of funds with the lowest return, what return must his fund have? (please round your answer to 2 decimal places). 2. Suppose the following data show the prices of 4 cars with similar characteristics that...

In the last quarter of 2007, a group of 64 mutual funds had a mean return of 0.8% with a standard deviation of 4.9%. Consider the Normal model N(0.008,0.049) for the returns of these mutual funds. a) What value represents the 40th percentile of these returns? b) What value represents the 99th percentile? c) What's the IQR, or interquartile range, of the quarterly returns for this group of funds?

In the last quarter of 2007, a group of 64 mutual funds had a mean return of 2.1% 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 negative 4.4% or less b)...
