**Homework:** Homework will be assigned but will not be turned in for a grade. In order to keep up with the material, it is *essential* that you keep up with the assignments on your own.

**Quizzes: **
There will be 4 quizzes for this course. The quizzes will be given during the labs. Students can choose to take the quiz during the 9:00am-10:00am lab or the 10:00am-11:00am lab).

- Quiz 1: Friday, July 6.

- Quiz 2: Wednesday, July 18.

- Quiz 3: Monday, July 30.

- Quiz 4: Friday, August 10.

I will drop the lowest quiz. Please see grading options below.

You have two options for your final grade. Option 1 is for students that would like for the quizzes to count toward their semester grade, and option 2 is for students that want their semester grade to be based only on the midterm exam and the final exam. Below are the two options:

Option 1: semester grade = 20% quizzes +35% midterm + 45% final.

The lowest quiz will be dropped

Option 2: semester grade = 45% midterm + 55% final

The final grade will be the higher value of the two options.

- The final exam will be given during class on Friday August 17 from 2:10pm-4:00pm. -- The final exam will be comprehensive, but the exam will focus primarily on material from chapters 6, 7, 8, 9, 10, and 11. Please bring a calculator.

- (8/08/07)

Students are allowed to bring one sheet (front and back) of hand-written formulas and/or notes to use during the final exam. Formulas will not be provided by the instructor for the final exam. Probability distribution tables for the Normal, t, Chi-squared, etc... will be provided. - Practice Final.
