CHAPTER 14 Introduction to Multiple Regression
14.49 The director of a training program for a large insurance
company has the business objective of determining which training
method is best for training underwriters. The three methods to be
evaluated are classroom, online, and courseware app. The 30 train-
ees are divided into three randomly assigned groups of 10. Before
the start of the training, each trainee is given a proficiency exam
that measures mathematics and computer skills. At the end of the
training, all students take the same end-of-training exam. The re-
sults are organized and stored in Underwriting.
Develop a multiple regression model to predict the score on
the end-of-training exam, based on the score on the proficiency
exam and the method of training used. For (a) through (k), do not
include an interaction term.
a. State the multiple regression equation.
b. Interpret the regression coefficients in (a).
c. Predict the mean end-of-training exam score for a student with
a proficiency exam score of 100 who had courseware app-
based training. ni botgmd
d. Perform a residual analysis on your results and determine
whether the regression assumptions are valid.
e. Is there a significant relationship between the end-of-training
exam score and the independent variables (proficiency score
and training method) at the 0.05 level of significance?
