Attendance: An attendance sheet will be passed around
during each class meeting. Attendance
is required but will not be given a grade. Be on time. Turn off your cell phone
in class.
Homeworks, quizzes and class project:
Ø
Problems will be
assigned at each class meeting and will be due the following class meeting. No
late homework will be accepted.
Ø
The class project will consist
on four assignments. These assignments are not independent of each other.
Ø
Any homework or class
project assignment not turned in at the regular class meeting must be deposited
in the instructor mailbox (Room 117, New West) before
12:30am on the due date. A grade of ZERO will be given to MISSING
homework or class project assignment.
Ø
There will be a maximum
of five quizzes or pop-quizzes in the semester.
Ø
Excel homework
exercises, along with auto-tutorial instructions, can be found at http://www.stat.unc.edu/teach/rosu/Stat31/Companion.html.
Ø
To receive credit for
the homework, the quiz or the class project, you must show all work neatly,
clearly LABEL each problem, CIRCLE your FINAL ANSWER, and STAPLE the entire
assignment together in the correct order with your FULL NAME printed on each
page. Only turn in Excel output corresponding to the template requested in the
assignment—do not turn in additional output. Not following the above rules will
hurt your homework: If you do not write your answers clearly (homework, quiz
or class project), you will get partial credit. If you do not staple or do not
write your name on your homework, you will receive a grade of ZERO for your
homework.
Ø
Each homework
assignment carries equal weight. Each quiz is worth double of a homework. Each
class project assignment is worth double of a homework. In total homework, quizzes and class project will
make up 30% of your course grade.
Ø
You may work with other
students on the homework assignments. Verbatim copying of homework is NOT
allowed and will constitute a violation of the Honor Code. Each student should
produce his/her own work to be graded.
After attempting the problems, a student is encouraged to seek help from
the Instructor during office hours or from Open Tutorial Leaders during Open
Tutorial Sessions. (The answers to the
even problems are in the book.)
Ø
Any questions regarding
homework grading should be discussed first with the Instructional Assistant. If
you are absent when a homework is returned, you may obtain your homework from
the Instructional Assistant.
Exams:
Ø
There will be 2
in-class Midterm Exams, each worth 20% of your course grade; the Final Exam is
worth 30%. All exams are required, and there will be no make-up exams. Missed
exams will receive a grade of zero.
Ø
All exams are closed
book and closed-note with no formula sheet permitted. Computers are not
permitted, but calculators may be used.
Ø
Any questions regarding
exams may be taken up with the Instructor. If you are absent when a test is
returned, you may obtain your test during the Instructor’s Office Hours.
Ø
Any student needing to
be excused from the regularly scheduled Final Exam because he/she has 3 final
exams within 24 hours must obtain a written Dean’s excuse and discuss the
situation with the Instructor at least 3 weeks before the regularly scheduled
Final Exam, so that alternative arrangements can be made.
