Yes, a small, fixed number of wrong answers on the marking key would
give the same result I suspect also. But it is interesting to me how
intuitively we discount the possibility that the one high score is a
random outcome, but rather the proof that the key is okay, or mostly
okay, and the class is low scoring.
