Investors in mutual funds keep a sharp eye on the total returnon their money. They also are

aware of the risk involved in their investment, commonlymeasured by a fund’s volatility (the

greater the volatility, the higher the risk). Below is a list of30 mutual funds randomly selected in

1998 from Fortune’s list of stock and bond funds,together with their 5-year total return (%) and

risk assessment:

Suppose that the question you wish to address using this data iswhether the total return on the investment is affected by the riskof the investment. You also want to know if you can predict thetotal return based on the risk. You will attempt a LinearRegression Analysis Using Microsoft Excel 2010 to help you answerthese questions.

Use Micrsoft Excel 2010 to run a linear regression analysis.What is the value of R2 (R-squared)?

QUESTION 5

What does this value for R2 (R-squared) suggest aboutthe linear equation that Excel determines as the line of bestfit?

This equation will be a very good predictor of related datavalues.

This equation will be an acceptable predictor of related datavalues.

This equation will be a poor predictor of related datavalues.

Inconclusive value

QUESTION 6

Identify the coefficients from the Excel Output summary that areused to write the line of best fit forthis data. If the equation was written as

                                                y= b1x + b0,

where y if the total return value andx is the risk,  what is thevalue of b0?

QUESTION 7

Identify the coefficients from the Excel Output summary that areused to write the line of best fit forthis data. If the equation was written as



                                                y= b1x + b0,



where y ifthe total return value and x is therisk,  what is  the value ofb1?

QUESTION 10

Use the line of best fit to predictthe total return (y-value) for a riskof  x = 11?

Value of r-square = 0.6808

Answer 5:

This equation will be an acceptable predictor of related data values.

Answer 6:

b0 = 2.2507

Answer 7:

b1= 1.1923

Answer 8:

When x = 11, the total return would be

y = 2.2507 + 1.1923*11

y = 15.366
