The Probable Pen in the Cereal Box
Final Results as of June 11, 1996
Whew! After a grueling end-of-semester, I have included all of the submissions that trickled in after the closing date. Our final solution included 2198 students. We have collectively purchased 34,313 boxes of cereal! That's nearly $100,000 worth of cereal. Click here to see the final submission list. Also, see the comments page.

And now a history of the mean and standard deviation:
