---------------------------------------------------
Ch.4: In some exercises, the authors use the language of "either A or B occurs" (exclusive or) when they should use "A or B occurs" (inclusive or) -- they clearly intend to allow the possibility that both occur. Interpret these exercises according to the authors' intended meaning.

Do not hand in the assigned homework from the text (unless there is some special instruction later). You should do the homework in an indicated section after we cover it in class, and before the next class. You can expect frequent quizzes testing whether you've done the homework.

The assignments above might be altered. You are responsible for keeping up with announced changes -- make friends in class to keep in touch with. Changes will also be emailed to the class and posted at the class web page.

There are solutions manuals on 2 hour reserve at the EPSL library under "Professor Boyle". These have solutions for almost all problems.

MINITAB assignments will be made separately, and these will be collected and graded.
