Homeworks

Homeworks count for 20% of your final grade. Homeworks will be posted at 2:00 pm every class day at our course site ( STOR155: Section 1 (Fall 2009)) at Blackboard and will be due at the start of the next class.

Homework Policies:

No late homeworks will be accepted. If you cannot make a particular class then drop of the homework in the Instructional Assistant's mailbox (Room 310, Hanes hall) by 1:50 p.m. on the day it is due. Please do not send homeworks via email etc.
Show all work and encircle the final answer for a numerical question (this is not required for an excel output). Please staple your homework in the correct order (the order in which the problems were assigned) before turning in the homework. Make sure that your name is printed on every page, while your section # as well as assignment # is written on the first page. Please do not use red ink as this will be used by the grader to highlight where mistakes that were made
Only turn in the Excel output corresponding to the template requested in the assignemnt. Do not turn in additional Excel worksheets or other output.
All homeworks will be graded and carry equal weight. A homework violating the 3 rules above will recieve a grade zero for the entire assignment.
At the end of the semester your worst 2 homeworks will be dropped, the rest of your homeworks will be averaged and will count towards 20% of your final grade
You are allowed to work with other students but the homework should be in your own words.
You are encouraged to meet the me or the Instructional assistant in their office hours for help on the homework problems after you have tried to solve the problems on your own. Any question regarding the homework grade should first be addressed to the Instructional assistant and if you still have questions then feel free to meet me. If you feel that some parts of a graded assignment should be regraded, please goto the Instructional Assistant within 2 weeks of getting back your assignment.
