Homework:
Homework will be assigned after each class meeting and will be due at the start of the next class meeting. No late
homework will be accepted. Any homework not turned in at the regular class meeting must be deposited in the Instructional
Assistant’s mailbox (Room 310 in Hanes Hall) before 1:00 p.m. on the due date; do not deposit in the Instructor’s mailbox, and do
not slide it under the Instructor’s door. Homework will not be accepted via email, disk, or any other electronic form. All homework
is required. Missed homeworks will receive a grade of zero.
Homework assignments will be posted shortly after class at our course site in “Blackboard” under Assignments.
“Blackboard” can be reached at the address http://blackboard.unc.edu and you will need to provide your “ONYEN” and
“PASSWORD” in order to login at “Blackboard”. Once you are in “Blackboard”, go to our course site entitled “STOR 155 Section
7 (Fall 2008)”, and then press the “Assignments” button.
To receive credit on homework, you must:
 show all work neatly, write in blue or black pen or pencil (never in red), clearly label each problem (including Excel
exercises), circle your final answers (circling is necessary only for numerical answers, and circling is not necessary on
Excel output), staple the entire assignment (including the Excel exercises) together in the correct order (the order they were
assigned) with your name printed in ink on every page;
 only turn in Excel output corresponding to the template requested in the assignment – do not turn in additional Excel
worksheets or other output.
Any homework violating these rules will receive a grade of zero for the entire assignment.
The homework will be graded, and each assignment carries equal weight, your semester average counts as 20% of your
course grade.
You are allowed to work with other students on the homework problems, however, verbatim copying of homework is
absolutely forbidden and constitutes a violation of the Honor Code; therefore each student must ultimately produce his or her own
homework to be turned in and graded. You are encouraged to ask the Instructor, the Instructional Assistant, and the Open Tutorial
Leaders for help on homework problems, after you have attempted to solve the problems on your own. The Instructor is available
during his Office Hours, the Instructional Assistant is available during his Office Hours, the Open Tutorial Leaders are available
during the Open Tutorial Sessions. Note the textbook provides the answers to the odd-numbered problems.
Any questions about your homework grades should first be taken up with the Instructional Assistant; if these questions
cannot be resolved with the Instructional Assistant, then feel free to discuss them with the Instructor. If you are absent from class
when a homework is returned, you can still get the homework back from the Instructional Assistant.
Exams:
There will be 2 in class Midterms, each worth 20% of your course grade; the Final will be worth 40% of your course grade.
All exams are required, and there will be no make-up exams. Missed exams will receive a grade of zero.
All exams are entirely closed-book and closed-notes with no formula sheets permitted; computers are not permitted during
exams, but calculators may be used.
Any questions regarding exam grades should be taken to the Instructor. If you are absent the day the exams are returned
you may pick them up at Office Hours.
Any student needing to be excused from the regularly scheduled Final Exam because he or she has 3 Final Exams within 24
hours must obtain a written Dean’s excuse and must discuss the situation with the Instructor at least 3 weeks before the regularly
scheduled Final Exam, so the alternative arrangements can be made.
