The quarterly returns for a group of 52 mutual funds are well modeled by a Normal model with a mean of 74% and a standard deviation of 38% Use the 68-95-99.7 Rule to find the cutoff values that would separate the following percentages of funds, rather than using technology to find the exact values a) the highest 50% b) the highest 16% c) the lowest 25% d) the middle 68%

The quarterly returns for a group of 52 mutual funds with a mean of 3.2% and a standard deviation of 5,8% can be modeled by a Normal model. Based on the model N(0.032,0058)what are the cutoff values for the a) highest 40% of these funds? b) lowest 20%? c) middle 80%? d) highest 80%? a) Select the correct choice and fill in any answer boxes in your choice below.

The quarterly returns for a group of 62 mutual funds with a mean of 2.8% and a standard deviation of 5.2% can be modeled by a Normal model. Based on the model N(0.028, 0.052), what are the cutoff values for the a) highest 10% of these funds? b) lowest 30%? c) middle 60%? d) highest 70%?

The daily exchange rates for the five-year period 2003 to 2008 between currency A and currency B are well modeled by a normal distribution with mean 1.303 in currency A (to currency B) and standard deviation 0.036 in currency A. Given this model, and using the 68-95-99.7 rule to approximate the probabilities rather than using technology to find the values more precisely, complete parts (a) through (d). a) What would the cutoff rate be that would separate the lowest 0.15%...

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...
