Comparing data distributions
The 25 students in Monsieur Beeckman's French class have been averaging just 72% on their tests, so they
have decided to do something very bad - 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%. The rest of the students successfully got 100%.
In Monsieur Blanc's class, the students were honest. Their scores approximated a normal distribution with a
mean of 75%
Which of the following is true?
Choose all answers that apply:
The standard deviation for Monsieur Beeckman's class is abnormally high.
The mean score for Monsieur Beeckman's French class is abnormally low.
The median scores for the two classes are essentially equal.
The mean scores for the two classes are very close.
