, Preface
The Test Bank contains a variety of multiple-choice, true-false, problem and fill-in questions based on the
definitions, concepts, and ideas developed in each chapter. In addition, numerical problems and
Microsoft® Excel computer output problems are also given with solutions provided in multiple-choice,
true-false, problem and fill-in format.
The Test Bank is intended to assist instructors in preparing examinations. The questions included herein
highlight the key topics covered throughout each chapter. The keywords after each question, and the
Keywords to Subsections Cross-reference and Subsections to Keywords Cross-reference are intended to
help instructors easily locate questions on a specific topic or concept. Explanation is provided when the
rationale of the correct answer to a difficult question is rather obscure. The format for the Test Bank will
facilitate grading and should be helpful to instructors who teach very large sections.
The intended difficulty level (easy, moderate, difficult) of each question in the Test Bank is stated in
order to facilitate test item selection by instructors wishing to create specific types of exams. However,
some words of caution must be given. The classification of question difficulty level is very subjective
and each question should be evaluated based on the emphasis the particular topic was given in class and
how much emphasis is to be given to numerical results obtained by calculator rather than computerized
results obtained from Microsoft® Excel. As an operational definition that is used here, items are classified
as easy if they pertain directly to definitions and fundamental concepts. Test items are classified as
moderate if they require some numerical calculations with more than a minimal number of steps or if they
require a broader understanding of the topic. Test items that are classified as difficult are done so because
of the level of rigor of the subject, the length of the narrative, the amount of effort required for solution,
or for responses that require more thought and analysis.
Instructors are also advised that all answers in the Test Bank are computed using Microsoft® Excel or
PHStat with no rounding involved in the intermediate steps. If students use rounding with formulae and a
calculator, their answers might be different from those provided in the answer keys. Likewise, if students
use the statistical tables at the end of the book instead of Microsoft® Excel or PHStat, their answers might
also differ from those provided in the answer keys due to rounding. Whenever possible, we provide
answers obtained using both Microsoft® Excel/PHStat and the statistical tables if they are very different.
This Test Bank and others that are similar suffer from one major weakness. They do not permit an
evaluation of the students’ written communication skill. The authors highly recommend that, if possible,
instructors who use this Test Bank supplement it with at least one short essay type question so that an
assessment can be made of the students’ understanding of concepts as well as how they can make
connections across various topics.
The following tabular display is a breakdown of the number of questions in each chapter by type.
