Math 3070-5: On-Line Course Syllabus
Spring Semester 2002

• The final exam will be given on May 7, 2002.
  
  Some of you have indicated that the time (8:30-10:30 p.m.) is inconvenient. We can try to get a room for this exam from 7:30-9:30 p.m. that day instead.
  
  The only way that this change can be made possible is if I hear, in writing, from all of you saying that this change is agreeable to you, and fits your schedule. If you feel that you want to change the time to that indicated above, you should email me before the end of April 26th and clearly say so. The only way that I will change the posted time is if I hear from all of you by April 26th, and in the affirmative.

• The final exam is open-book but closed-notes.

  Make sure to bring your books and calculators.
• Practice Final Exam:
  1. Solve Midterm #2, and the homeworks.
  2. A new quality training program is being tested at an auto parts manufacturing plant. For one type of part, the following table gives the numbers of defective and good parts manufactured in the week preceding and the week following the program:

     Quality	Before	After	Total
     Good	121	154	275
     Defective	46	19	65
     Total	167	173	340

     Do these data suggest that the program is effective?

  3. According to a survey sponsored by the American Society for Microbiology, 50% of the people using the restrooms in New York City's Penn Station do not wash their hands after going to the bathroom (Associated Press, Sept. 19, 2000).

     Suppose that you observe 427 people who fail to wash their hands in a random sample of 1,000 people from Penn Station. This is less than 50%; is this discrepancy real or due to chance? Use this data to test the claim made by the American Society for Microbiology at 95%.

  4. Oncology Nursing Forum (July 2000) published a study of the effects of advanced nursing care on quality of life of women with breast cancer. Breast cancer patients were randomly assigned to either an intervention group or a control group. All patients received standard medical care, but those in the intervention group received additional care from an advanced practice nurse (APN). The next table describes the number of patients who needed to make at least one emergency room visit doing the study period. Are the percentages of breast cancer patients who make emergency room visits for the two groups the same or is the one higher for the control group?

     	Control Group	Intervention Group
     Sample Size	74	78
     Number who made emergency room visits	71	58

  5. Exercises on pp. 353-357.
