The quarterly returns for a group of 59 mutual funds with a mean
of 3.8% and a standard deviation of 6.9%

The quarterly returns for a group of 58 mutual funds with a mean
of 3.4% and a standard deviation of 4.3% can be modeled by a
Normal model. From these funds, find the cutoff return value(s)

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)

You are considering two mutual funds as an investment. The
possible returns for the funds are dependent on the state of the
economy and are given in the accompanying table.
State of the Economy Fund 1 Fund 2 Good 42 % 46 % Fair 18 % 25 %
Poor −4 % −17 % You believe that the likelihood is 10% that the
economy will be good, 40% that it will be fair, and 50% that it
will be poor. a....
