CS109 Final
Thur Dec 9th, 12:15pm

Overview

The CS109 final is a 3-hour, closed book, closed calculator/computer exam. You are, however, allowed to bring 15 pages (front and back) of notes in the exam, formatted in any way you like. Make sure to practice before the exam.

Location and Time

When: 12:15pm to 3:15pm Dec 9th
Where: Hewlett 200

Coverage

The final will be comprehensive of all the material in the course through class on Nov 19th. It will place special emphasis on the content covered on the psets, and will have more material from concepts that were not already covered on the midterm.

Answer Format

You are going to be solving probability questions by hand. To that extent we are not interested in numeric answers, but rather in formulaic answers. It is fine for your answers to include summations, products, factorials, exponentials, and combinations, unless the question specifically asks for a numeric quantity or closed form. Where numeric answers are required, the use of fractions is fine. You must show your work. Any explanation you provide of how you obtained your answer can potentially allow us to give you partial credit for a problem. For example, describe the distributions and parameter values you used, where appropriate.

What about the Phi table? If it comes up on the exam, I am not going to make you look up values from a phi table. Instead you can leave your answer in terms of phi (the CDF of the standard normal). For example $\Phi(\frac{3}{4})$ is a fine final answer. This was not the case in the past so you will see questions which ask for a numeric answer in the practice exams.
