**Homework**
In each assignment there will be two sets of exercises, most of which
are from our textbook. You should work the first set, but you won't be
asked to hand in your solutions.

The second set is due on the date listed in the course schedule, at
the beginning of class. You should do these exercises completely and
carefully. The exercises require you to use the computer.
If necessary, you should complete these assignments outside of the
scheduled lab hours.

**Examinations:**
There will be two midterm exams and a final exam. The exams will
be "closed book". You may bring a calculator to the exam. The final
exam will be comprehensive.

I will use "Grading on the Curve" to convert the scores into letter grades
This means that your grade will be determined by two numbers:
**the mean** m, and
**the standard deviation** σ.
**Study statistics to learn what they are!!!**

Scores above *m*+.7σ will earn A or A-. Scores between
*m*-.4σ and *m*+.7σ will earn a B+, B, or B–.
Scores between
*m*-1.2σ and *m*-.4σ will earn a C+, C, or C–.
Scores between
*m*-2.2σ and *m*-1.2σ will earn a D+, D, or D–. And
the
scores below *m*-2.2σ will fail the course.
**GRADING SCALE (Percent):**
A |
A- | B+ | B |
B- | C+ | C |
C- | D+ | D |

*m*+.9σ | *m*+.7σ |
*m*-.3σ | m-.1σ | *m*-.4σ |
*m*-.8σ | *m*-σ |
*m*-1.2σ |
*m*-1.7σ | *m*-2.2σ |
