Coverage

The final will be comprehensive of all the material in the course through class on March 7th. 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.

Practice

Note that TAs will not be required to know all the answers on these practice exams, so if you ask questions about them in office hours, or on Ed, please give full context.

Review Session

A series of Final Review videos will be posted by Saturday noon.

You can do it!
