Math 160 D

Fall 2011

Assignments

Assignments are due in class on the due date.

Please show your work (where appropriate). Problems with only an answer may not receive credit (This is true for both homework and exams)

Please note that answers to odd-numbered questions may be found in the back of the book. Answers for these questions will not be given credit without supporting detail.

When turning in an assignment, please turn in only that assignment - not any late assignments you might have. Late assignments should be turned in to me separately, and late assignments can not be accepted after the graded assignment is returned to the class.

There will be two varieties of exercises in this course.

The first sort will be basic, generally short answer questions usually taken from the textbook. These will be assigned generally once a week, and will usually be 10 points.

The second sort will call for critical analysis and professional writing. These exercise will generally be taken from a group of textbook exercises, but you will be asked to write as if you are writing a report. You should open with a description of the problem (which can be, for the most part, taken from the problem write-up(s)), proceeding then to respond to the individual questions, writing as if for a formal report (and not for a homework assignment), integrating graphs and other documents from MiniTab into the text (use MS Word) and not as a series of appendices. These final reports should printed out from an appropriate word processing program (such as MS Word). These questions will be given greater weight than the basic type I questions.

Late assignments are accepted with an increasing penalty until the graded assignment is returned to the class, after which time late assignments are not accepted. All materials must be submitted by class time on the last day of class. Unless otherwise specified, all assignments must be submitted in hardcopy in class.

Note on essay/discussion/comment questions. These are very important parts of an exercise. Please respond with a thoughtful, well-written paragraph (more if the question calls for it). (NEW!)

Assignment #10, due Thursday, December 1. This is a problem of the second type described above and has the requirements described above. Please work problems 7.81 and 7.82 on page 457 writing as if you were writing for a formal report. While we do not have the capability in MiniTab to produce back-to-back stem-plots, please use side-by-side box-charts and also provide histograms and probability plots, describing carefully what these tell you. Answer the questions in problems 7.81 and 7.82 but as you would if the problems were an outline for your report (that is, I do not want to see "Problem 7.81 (a)" anywhere in your report. This problem will be worth 20 points, and a significant part of your score will depend on the quality and professionalism of your writing and on your adherence to the standards given above. In particular,

Work with handwritten text or graphs will not be accepted, and
Work with graphs appearing at the end of the report will not be accepted. Any graphs/exhibits must appear within the text at the point at which they are being discussed.

Assignment #2, Due Friday, September 16. Please work

On pages 31 - 40, problems 1.48, 1.51, 1.52, 1.54, 1.55, 1.56, and 1.57. On these exercises, do not use any statistical software, and show your work (numbers by themselves will not receive credit in most cases).
On page 46, work problems 1.62, 1.63, and 1.64. Please use Minitab for these exercises (even if Minitab's way of calculating quartiles and such may differ from the textbook's method). Discussions / explanations should be professionally written and part of the grade will depend on the quality of your writing. I did see three outliers in the data for the first two exercises instead of just the one. Please do the exercises using the low outlier.

Assignment #1. Due Friday, September 9 (Please note change in due-date). Please work

On pages 22 - 27, problems 1.14, 1.16, 1.19, 1.33,1.34. Since MiniTab does not support back-to-back stemplots (at least not at last check), feel free to use multiple boxcharts instead (we'll see how to do this in class - if I forget to do this in the first week, please remind me).
Data for 1.33, 1.34 can be found in the minitab data file GLUCOSE (more details later). However, please be ready to do this without the software on an exam
This exercise will be worth 10 points.
