Question
1
Shown
below are rental and leasing revenue figures for office machinery and equipment
in the United States over a 7
year
period according to the U.S. Census Bureau. Use these data and the regression
tool in the data analysis tool pack to run a linear regression.
Based on
the formula you get from the regression output, answer the following questions:
a)What
is the forecast for the rental and leasing revenue for the year 2011?
b)How
confident are you in this forecast? Explain your answer by citing the relevant
metrics.

Question 2
Suppose a researcher gathered survey data from 19 employees and
asked the employees to rate their satisfaction on a scale from 0 to 100 ( with
100 being perfectly satisfied). Suppose the following data represent the
results of the survey. Assume that the relationship with supervisor is rated on
a scale from 0 to 50 (0 represents a poor relationship and 50 represents an
excellent relationship); overall quality of the work environment is rated on a
scale from 0 to 100 (0 represents poor work environment and 100 represents an
excellent work environment); and opportunities for advancement is rated on a
scale from 0 to 50 (0 represents no opportunities and 50 represents excellent
opportunities).
Answer the following questions:
A) What is the regression formula?
B) How reliable do you think the estimates will be based on this
formula? Explain your answer by citing the relevant metrics.
C) Are there any variables that do not appear to be good
predictors of job satisfaction? How can you tell?
D) If anew employee reports that her relationship with her
supervisor is 40, rates her opportunities for advancement to be at 30, finds
the quality of the work environment to be at 75, and works 60 hours per week,
what would you expect her job satisfaction score to be?

Question 3
Investment analysts generally believe the interest rate on bonds
is inversely related to the prime interest rate for loans; that is bonds
perform well when lending rates are down and perform poorly when interest rates
are up.
Use the following date to construct a scatter graph and then fit a
regression line to the date. Report the regression formula and the rsquared
values from the chart (right click on the data points, select Add Trend line,
and selection options to show these metrics).
Do you think the bond rate can be predicted by the prime interest
rate? Justify your answer using the relevant metrics.
