Required Materials

   • Text: Applied Statistics and Probability for Engineers 4th Edition, Montgomery and Runger.
     (Available at IMU Bookstore.)

   • WileyPLUS online component for the text (Bundled at IMU Bookstore or use the e-book
     contained in WileyPLUS as substitute for the hardcover text.)

   • Calculator: Your calculator must be able to calculate one-variable statistics and two-variable
     statistics. Use the Calculator Help link on the Stat 39 website to check whether your calculator
     will do the job.
     Some calculators which are recommended: TI 83 Plus, TI 86, TI 30XIIS, TI 36X, TI 36XII.
     (Some of these have elaborate spreadsheet-type displays, and some do not.)
     The following calculators will not do the job (no two-variable statistics) and should not be
     purchased: TI 30STAT, TI 30X, TI 30Xa.

Course Policies Course policies are governed by the College of Liberal Arts and Sciences.

Disabilities Please see me in my office as soon as possible if you have any disabilities which
require alternative arrangements for lectures or exams.

                                       Course Features
  1. Students complete reading assignments before class. Please Note: Students are respon-
     sible for class notes, and must get them from other students in case of absence.
  2. Use textbook + supplementary notes in class.
   • Homework is assigned with due dates, but is not collected. Quizzes over homework are given
     instead. Completing homework on time is absolutely vital to success in Stat 39!
   • Students compare their homework answers to homework solutions (posted on website), then
     work to overcome incorrect answers. This overcoming adversity pays off on exams!
Weekly Discussions
   • Homework Quiz (similar to problems on HW assignment due that week.)
   • Worksheet with practice problems to help with the next HW assignment.
Homework Help
   • Primary sources: Textbook reading, WileyPLUS, course notes, Discussion worksheets
   • TA’s and Prof. Whitten’s office hours
   • Stat Dept. Tutor Lab (free help beyond office hours) — See course web site for a link to Lab
     weekly schedule and location.
   • Students who work together with a study partner or in a study group tend to do better than
     students who work alone in Statistics courses. (Although don’t rely on a study group to avoid
     doing the homework problems yourself!)

Computer Projects The course includes two projects in which computers are used to perform
statistical calculations on data. We use MINITAB Version 14 statistical software, available at all
ITC’s on campus and in the College of Engineering, or for personal download for $30. Students
write a project report to describe their conclusions.

   • Two midterm exams and a (comprehensive) final exam
   • Multiple-choice format, closed book
   • For Midterm Exam 1 and Midterm Exam 2, students may use one standard sheet of paper
     (8.5 by 11 ), front and back, of handwritten or word-processed formulas and notes.
   • For the Final Exam, students may use three standard sheets of paper, front and back, for
     formulas and notes.
   • Exams practice questions are available on the website which show the general exam style.
     But the content of new exam questions will differ.

ICON Students can access exam and Discussion quiz scores on ICON. (See ICON link from
website.) Online quiz scores are accessible on WileyPLUS.

Email Professor Whitten sends emails to the class containing important or useful information.
Please keep your UI email account clear (under quota) so that you will receive such messages.


Grades in Stat 39 are calculated according to the noncompetitive scale shown below. (This means
that your grade is based on individual performance rather than forced into a category by the
arbitrary percentages of a competitive scale.)

Professor Whitten reserves the right to liberalize the grading scale (reduce required minimum course
percentages) at the end of the course, in case such an adjustment is warranted by unusual and rare

   • Discussion HW quizzes are time-sensitive, and no makeup quizzes are given. But as an
     allowance for necessary absence (university-sanctioned events, illness, family emergency, etc.),
     the two lowest Discussion HW quiz scores are dropped from the calculation of the course grade.
     (No online HW Quiz scores are dropped.)

   • If your Final Exam score exceeds either the Midterm Exam 1 score or the Midterm Exam 2
     score, the smaller of the two midterm scores is replaced with the Final Exam score in the
     calculation of the course percentage. (At most one midterm score is replaced.)

   • Weights for course percentage:
        10%      Online (WileyPLUS) HW Quizzes
        10%      Discussion HW Quizzes
        10%      Computer Projects
        22%      Midterm Exam 1
        22%      Midterm Exam 2
        26%      Final Exam
   • You can calculate your own course percentage as follows:

         1. Drop your two lowest Discission HW quiz scores. From the others, calculate a Discussion
            quiz percentage. Similarly, calculate an Online HW quiz percentage (with no drops) and
            a Computer Project percentage.
         2. Replace your lowest midterm Exam score with your Final Exam score only if such
            replacement improves your score (at most one such replacement.)
         3.      Course % = (0.10)(Disc HW Quiz) + (0.10)(Online HW Quiz) + (0.10)(Computer Project)
                 + (0.22)(Exam 1) + (0.22)(Exam 2) + (0.26)(Final Exam)

   • Course grades are earned according to the following minimum course percentages:

     A        92%     A−   90%     B+     88%
     B        82%     B−   80%     C+     78%
     C        72%     C−   70%     D+     68%
     D        62%     D−   60%
     F        Below 60%

     For instance, a course percentage of 87.99% earns a grade of B in Stat 39.
