Chapter 4
Review Problems

The problems in this chapter range across the whole course, and each one draws on several chapters at once: a definition, a distributional calculation, an estimator and a test may all appear in the same problem. They are the best test of whether the material holds together.

Read each problem, put the notes away, and write your own answer before opening the solution. A worked problem read passively teaches almost nothing; the same problem attempted first is the best preparation there is.
