Our second midterm will be on Friday, November 21, 12:00 - 12:50, in Humanities A51. It will cover everything we do up to that time, after the first midterm: in class (after October 22), in the book, in the homework (assigned after October 22), and in the online supplements.
Remember that the lectures are webcast.
For the book, the test covers the three sections:
12.4 (from page 836),
12.5,
12.6.2.
For the homework, it covers all
problems
assigned from these sections (after October 22).
Moreover, we have five online supplements:
a discussion of
Poisson processes,
a summary of some of the facts about
six distributions we have studied
(and in addition there is the multinomial distribution),
a discussion of
aging,
a summary of the four
limit theorems from Section 12.6 (only the central limit theorem
is covered on this midterm),
and a discussion of the
pill problem.
Ground rules: Paper will be provided. Bring pencil and eraser. No calculators (an answer of pi/ln 2 should be left like that). But an answer of P(9,3)/4! should be worked out. Closed book, except that you may bring a 3 x 5 note card, if you wish (with writing on both sides). After the test, keep the note card for the final exam. A copy of the table on page 919 will be provided. Please bring your photo ID to the tests.
The test problems will be mostly like the homework. ("Mostly" means mostly, and "like" means that I think similar methods are used.) Answers should be supported by the work shown.
Jennifer Padilla will hold a review session on Friday, November 14,
at 6 pm, in Boelter 5249.
Benjamin Shargel will hold a review session on Thursday, November 20,
4-5 pm, in MS 5137.
I will hold a "last chance" question-and-problem session on
Thursday , November 20, 5:30 p.m., in MS 6627.
And questions can always be posted on our
virtual office hours board.
We have posted a practice test,
in pdf format.
Disclaimer: No claim of completeness is made;
there are other sorts of problems.

Note: Any requests for regrades should be received by December 5. Tell me what you think was overlooked, misinterpreted, or misjudged. I will reexamine the entire test, and may assign a higher or a lower grade. (Needless to say, the test must be unaltered; we keep photocopies of some pages from some tests.)
