Notes:

• Show enough work on all problems to convince me you know what you're doing. If your work consists of using a graphing utility, then show the graph.
• Numbers 1, 4, 5, 6, and 7 should be worked by hand, not using the graphing utility, although a graphing utility can be used to check the results.
• All problems are directly from the textbook, but they may be odd or even.
• You may bring in a note card with instructions on how to use your calculator to use work the linear regression problem (#11). The notes must pertain to the calculator use only, and may not contain worked out problems.
