If you send email to the instructor,
please put "Stat 362" in the subject line.
Although the general schedule of the course will remain essentially as
shown below, this web page will evolve as the semester progresses. In
particular, links to solutions to assignments and quizzes will be posted
at appropriate times (after the fact, of course!).
The general description of the course is available at
www.science.gmu.edu/~jgentle/stat362/
The final exam is December 17 at 1:30.
This is right at the end of the exam period, and of course we'd
all like to take the exam earlier, so don't even ask! (although
I'm sure your excuse is good)
