EDITION OF TRIOLA’S ESSENTIALS
Write your name and class time and clearly separate sections! See syllabus.
Show work where appropriate, and use “good form and procedure,” as in class!
This is due when you take Quiz 1.
Graded out of 10 points.
“*” denotes “See Hint/Comment below.”
Answers to the “evens” may be provided later in class (not online).
“Look at” means “skim, but you don’t have to do.”
The answers to “My Problems” are at the end.
Homework exercises are typically given under “Basic Skills and Concepts” and
“Beyond the Basics.” I will often tell you how to round off on test problems; on the
homework, you may peek at the answers so that your rounding method is
consistent with the book’s. Note: The book and the solutions manual sometimes
use “=” (exactly equal to) when they should use “
±
” (approximately equal to).
You should read the introductory “Chapter Problems” and Margin Essays; they’re
interesting and useful!
CHAPTER 1

7. Section 14 has interesting questions that will test your critical thinking
abilities. Section 15 discusses survey sampling when conducting a study.
