and Supplementary Exercises. Use the index at the end of the book to locate definitions.
Problems: Start the problems listed here
immediately after the section is started in class. As you read a chapter, do
the odd number “Apply
your Knowledge” and all “Check your Skills” multiple choice problems. Check the
“Apply your Knowledge” and
“Check your Skills” problems and the odd number exercises against
the answers in the back of the book, and keep working on them until you can get
that answer. You may refer to the student solution guide, or discuss the
problems with your classmates or a tutor or me.

Instructions for 2.48

The 4Step Method is described on p.55. Follow that method and show the
four steps (STATE, PLAN, SOLVE, CONCLUDE) in your answer.

Carefully describe the variable and give its units of measurement in
your STATE step.

Example 2.9, p. 56 and 57, is similar to 2.48.
Use it as a model for your solution.

In PLAN mention the specific graphs and calculations you will use.

Do stem plots like in figure 2.4. Find means and standard deviations by
using a calculator or computer program, NOT a table like example 2.7.

In the conclusion describe how your answer is based on the means,
standard deviations and stemplots.
