Chance, too, which seems to rush along with slack reins, 
is bridled and governed by law.

Things to be Handed In

For this class you should do most of the problems at the end of each section.  I will not assign specific problems, rather during each class, you will take a short quiz over the concepts in the sections covered the class period before.  This will count as your homework and will be 15% of your final grade. 

Computers with Minitab installed on them are located in PE 422 Computer Lab and the Woldt Computer Lab. Click here for MiniTab Instructions.
