Stat 20 Fall 2003 Section page

GSI: Ben Bolstad email:


The aim of this page is to keep notes of what was covered at my sections of Stat 20 (Fall 2003). I will try to keep up to date notes on this page, but there may be occasions where it lags what is covered during our discussion. Notes will never appear here until after the section has already occured. It is in your best interests to always attend the section hours. More thorough discussion will likely occur at the sections. Occasionally, in the material here, I will provide solutions. But usually it will only be a listing of the problems covered. Please be sure to let me know of any typos etc.
