Homework rules

You may work with other students on figuring out how to work homework problems, but you must write up the solutions on your own and in your own words.
Acknowledge your sources (people and texts). This is part of academic honesty.
In nontrivial problems, show how you get your answers.
If you use your calculator to get answers, indicate that in a checkable way, e.g.,
normalcdf(0, 240, 266, 16) = .0521 approximately.
Turn in neat, well-written solutions, not messy first drafts. Trim "fringes." Staple.
Turn in homework on time. Late homework will not be graded, but your lowest two homework scores will be dropped.
Do extra credit entirely on your own. Turn it in separately.
