Course Information





There will be two midterm exams and a cumulative final exam. The first midterm will be held on Thursday, October 4 and the second midterm will be held on Thursday, October 26, both from 7-9 PM in Rockefeller 001. If you are unable to make an exam, it is your responsibility to notify your instructor at least 24 hours prior to the exam and arrange a make-up time.

The final exam will be on Friday, November 16, from 3 PM-6 PM in Kemeny 007.

Midterm 1 List of Topics
Note that there will be a small Matlab component to Midterm 1. You will be given some Matlab code for a function, and you will be asked to describe what the function does. Nothing will be more difficult than the functions we've created in class or homework.

Midterm 1 from Summer 2009
The first eight questions are on Probability Online, and you can check your answers there. The final two questions are on expected value, which will be on Midterm 2.

Midterm 1 from Summer 2011
Questions 6(b) and 7(b) will be covered on Midterm 2, and you shouldn't worry about the bonus question. If you see references to "stars and bars," think of our "letters and mailboxes" homework problem.

Midterm 2 List of Topics
This includes a list of problems from the previous years' midterms to study from. Again, all selected problems either have solutions included or are on Probability Online. Also, the second page is a table of expected value and variance for the important discrete distributions. This page will be attached to the end of Midterm 2. Note that the table does NOT include the definitions of the distributions; you should memorize these.

Midterm 2 from Fall 2011

Midterm 2 from Summer 2011

Final Exam List of Topics
This includes a table of expected value and variance, plus a couple other formulas, which will be attached to the end of the final exam. The normal distribution table will also be attached.

Final Exam from Summer 2012
Questions 7(c)(d)(e) will not be covered. Question 3(b) is on hypothesis testing, which we haven't specifically covered, but you still have all of the tools to solve it. Question 11 will require some puzzling out, but you should get it.
