Problems and solutions (6th edition)

The way to understand this stuff is to do problems. Any of the problems in the text are worth doing; the odd-numbered ones have answers at the back. The problems listed below seem especially useful. Detailed solutions for these can be found by clicking on the links in the table.

For a lot of the textbook problems, it will help you to use StatCrunch.

The problems as listed in the textbook have the chapter number prefixed; thus, problem 13 in Section 1.1 is actually Exercise 1.13 in the textbook.
