In Monsieur Beeckman's French class, the 25 students have been averaging just 72%, percent on their tests, so they have decided to do something very bad -−minus cheat on the final exam. They've stolen a copy of the test and memorized all the answers. For 13 of the students, however, justice was swift. They accidentally got last year's copy of the test and each of them failed with a 50%, percent. The rest of the students successfully got 100%, percent. In Monsieur Blanc's class, the students were honest. Their scores approximated a normal distribution with a mean of 75%, percent.
