### Schedule

The schedule below is a record of what we have actually done as well as an approximate projection of what we will do. Course materials will be posted here and distributed in class. WeBWorK assignments will be posted as they are assigned. Suggested exercises for each section are odd only (unless otherwise specified). Solutions to odd-numbered problems in both books are available (here for Grinstead & Snell and at the back of OpenIntro Statistics). Challenge problems are marked with an asterisk (*).
