, Section I
Test Bank
The first section of this Instructor’s Manual consists of a test bank of exam
items to accompany the Statistics textbook. There are approximately 25 multiple-
choice questions, 25 true/false questions, and a handful of other text questions for
each of the 19 chapters in the book. Answers are provided for all of the test items,
and the multiple-choice and true/false questions are cross-referenced to specific
pages in the textbook. Finally, you should note that some of the exam items are
marked with a www to indicate that these items are available to students on the
Study Center web site at www.wadsworth.com.
