Problem 113E
Entry-level job preferences. Benefits Quarterly (FirstQuarter, 1995) published a study of entry-level job preferences. A number of independent variables were used tomodel the job preferences (measured on a 10-point scale)of 164 business school graduates. Suppose stepwise regression is used to build a model for job preference score(y) as a function of the following independent variables:
a. How many models are fit to the data in step 1? Givethe general form of these models.
b. How many models are fit to the data in step 2? Givethe general form of these models.
c. How many models are fit to the data in step 3? Givethe general form of these models.
d. Explain how the procedure determines when to stopadding independent variables to the model.
e. Describe two major drawbacks to using the final stepwisemodel as the best model for job preference score y.

ANSWER:Step 1 of 6
It is given that a number of independent variables were used to model the job preferences
of 164 business school graduates.
Dependent variable:
y = Job preference score
Also we have 7 independent variables.
