**Ms. Sue**, Sunday, August 9, 2009 at 9:12pmI don't think so.

The number of courses remaining until graduation will be far different for the students -- depending upon how many courses they've already taken. The freshmen will have the most courses remaining, while the seniors will have the fewest. Since there are probably more freshmen than seniors, the number is probably skewed with the biggest proportion being in the freshmen class.

The scores of AP math students will probably show a normal distribution.

**Ms. Sue**, Sunday, August 9, 2009 at 9:30pmSince the scores of AP students probably show a normal distribution, the answer can't be D.

Do you understand "normal distribution?"
