Stats 515, Statistics I, Sections 2 and 5
Fall 2017

This is the webpage for Sections 2 (MWF 12:20-1:10) and 5 (MWF 11:15-12:05), taught by Michael Sullivan. For information that is uniform throughout all sections of Stats 515, such as exam info, textbook, TA office hours, etc, please consult the coursewide webpage .

The instructors' 30% for Sections 2 and 5 will be based on weekly written HW, weekly online WebWork HW, and possibly several in-class quizzes.

Typically, WebWork will be due Tuesday evenings and written HW will be due Friday in class. There may be some exceptions due to exams and holidays. At some point later in the semester, the WebWork HW will end and the written HW will become longer. Discussion of homework and practice problems with fellow students is encouraged but you must submit your own work.

For the written HW, make sure your name is on every page and your work is stapled. The grader is not responsible for lost sheets. If you have any issues/questions with the grading, ask the grader Dongah Kim (dkim at math dot umass dot edu) by email or at their office hour. If you are not satisfied, please bring the issue to me. Due to limited UMass resources, not all problems will be graded.

NOTE: I will not accept late homework. One missed homework assignment is allowed. For the exceptional (documented) situation, please discuss with me.

My office hours are (tentatively) Monday 10:00-11:00, Weds 10:00-11:00, Weds 1:15-2:15, and by appointment Monday and Wednesday. I am usually off-campus on Tuesday and Thursday. I might hold extra office hours the day of the exams. Check back here closer to the date. All my office hours are in LGRT 1323G.
