Calculator: You will need a scientific calculator having statistical functions. The recommended models are the TI-30X IIS, TI-34 II, TI-36X, TI-83 Plus, TI-84 Plus, TI-89 and TI-89 Titanium. These recommended calculators may be used on tests and on the final examination. Text-capable or networked devices are prohibited.
Objectives: To develop experience with notions of probability and elementary statistical analyses.
Outcomes: Course participants should be able to discuss topics in probability, as well as use statistical procedures to analyze basic scientific or econometric questions.
Assessment: The course grade employs a total of 600 points. Each student’s grade will be based upon the percentage of points earned according to the following scale.

  Tests (2 @ 100 pts. ea.) 200 pts.  
  Quizzes (10 @ 10 pts. ea.) 100 pts.  
  Homework (5 @ 20 pts. ea.) 100 pts.  
  Project (1 @ 50 pts. ea.) 50 pts.  
  Comprehensive Final Examination 150 pts.  
 
  A - 90% 540 - 600 pts.  
  B - 80% 480 - 539 pts.  
  C - 70% 420 - 479 pts.  
  D - 60% 360 - 419 pts.  
  F <= 359 pts.  



  1. Tests   There will be two 100 point tests and a 150 point comprehensive final examination. You’ll need to show your work in writing on test problems in order to receive full credit. Problems presented on quizzes and tests may not be exact ‘clones’ of problems found in the text, and some independent thought may be required. If you must miss a test, you’ll need to make an explicit agreement with the instructor in advance of the scheduled test date for a make-up test. Tests will occur as per the attached class  schedule . Phone messages relating a student’s inability to attend a test will not be accepted as a rescheduling arrangement. YOU MUST TALK TO THE INSTRUCTOR BEFORE THE TEST TO ARRANGE A MAKE-UP TEST.



  2. Quizzes   Quizzes will occur at the beginning of class meetings and are then reviewed at the subsequent meeting. Approximately 12 quiz scores will be recorded during the semester, of which each student’s highest 10 will be used in calculating the quiz grade. When you are absent from class, you’ll need to notify the instructor on the day of the quiz in order to make up quizzes that you miss. All students must make up missed quizzes within two weeks of the day the quiz was presented.

  3. Homework   Daily homework assignments (as described in the  assignment  sheet) will not be turned in for a grade. However, homework review/problem solving sessions based on this material will be held after the quiz at each class meeting. Five short homework assignments requiring more careful write-ups will be assigned and turned in for 20 points each. Students must submit typed hardcopy for these assignments, and they should be turned in on the day the instructor asks for them in class. Homework that is turned in late will be subject to penalties. Homework turned in more than four weeks after the due date will receive no credit.

  4. Project  The hypothesis-testing project will be assigned during the last month of classes. This assignment requires a carefully presented typed hardcopy submission that will be turned in for a maximum score of 50 points. This assigment will be due on Friday April 20. Points may be subtracted for late submission. Projects turned in after the date of the final examination will receive no credit.

  5. Final   The  final examination  will be written by the Mathematics Department. The final examination will occur at 3:00 - 5:00 PM on Wednesday April 25. Phone messages relating a student’s inability to attend the final examination will not be accepted as a rescheduling arrangement. YOU MUST TALK TO THE INSTRUCTOR BEFORE THE TEST TO ARRANGE A MAKE-UP TEST. DO NOT SCHEDULE PERSONAL TRAVEL PLANS THAT MAY CONFLICT WITH THIS DATE.

  6. Attendance   Class attendance is expected. Attendance will be not be formally recorded, and it is not included in grading procedures. When you miss a class, it’s strongly recommended that you contact other students or the instructor to get up to date on announcements, homework, etc. The instructor reserves the capability to withdraw a student from the course once that student has exceeded nine class absences. This action may, or may not, be taken by the instructor.

  7. Assignments   Students should read all sections of the textbook mentioned in the class schedule, and are responsible for this material. It’s very important to attend class regularly and extremely important to work through daily homework assignments in a timely fashion. Keep in mind that it can be very difficult to catch up once you fall behind on the course material.

  8. Accommodations   Students with disabilities are personally responsible for arrangements to use physical or academic accommodations associated with this course. Failure to make those arrangements with the instructor and the Coordinator of Academic Accommodations in a timely fashion may negatively impact your grade. Students with registered learning, physical or psychological disabilities, who require accommodations for this course should contact both the instructor and the Coordinator of Academic Accommodations: Ryan Sweet at (330)490-7324, to begin delivery of services. If you received accommodations at other educational institutions, but have not yet registered your status with Walsh University, or if you believe you may have a disability and need to get accommodations for it, contact the Director of Counseling Services: Francie Morrow at (330)490-7348 or fmorrow@walsh.edu, to begin delivery of services.

  9. Integrity   Students are responsible for their academic work. Plagiarism and other forms of cheating or academic dishonesty may result in a failing grade on a test, a failing grade for the course, or possibly suspension from the university.
