**Announcements**

- I will have a
**review session**for questions related to the final exam next Monday evening (May 8), from 8:00 pm -- 9:30 pm in SH-DH**351**(not room 215 as previously announced). - I will have
**office hours**Tuesday, May 9, from 3-5 and on Wednesday from 2-3:30. - I am
**missing scores**for some of you for one or two assignments. To make sure there is no error in the recording of grades, please let me know if you have the missing assignment. If you didn't seem to do any assignments, I omitted your name from the list. I have updated the list to**include PS #5**, which quite a few of you evidently did not do.Name1 ps1, ps3 Name2 ps2, ps5 - Some
**review notes**on regression are here . Its 10 pages long, so I do not have copies to distribute. Have a look, and print it if you want a paper copy. Evidently, the printed version is a lot more easy to read than when you view the document with Acrobat. - The
**final exam**is on Wednesday, May 10The

**make-up final exam**is scheduled for Friday, September 8, 2000, from 4-6 pm. If you do not take the final exam on May 10, you will be required to take the make-up final next fall. - The average for the second exam was 85 with an SD of 14.
The median was 91 and mode was 92.
- The mean for the first midterm was about 80 with SD = 13.
You can figure out your relative standing from these summaries since
the grades are close to normal - albeit a bit skewed.
- I have the impression that some of you are not aware of the
**grading distribution**for the material in this class. I have given them when asked, but not published it here. It was in the class syllabus. Here it is:- Homework 10%
- Project 10%
- First test 25%
- Second test 25%
- Final 30%

- For
**questions related to the project**please look at the list of "frequently asked questions" here . - For JMP questions, you should always see the TAs at the Stat Lab for help. They are there most of the day M-F and can show you how to use JMP for doing the calculations. Their schedule is on the class web page.

For the datasets from the regression casebook, go to this link.
