Answer:

a.the average size of a seventh-grade class is larger and varies more than that of a kindergarten class

Explanation:

ok so we know the mean and the m.a.d of both data sets, so now all we have to do is analyze the data

so the class ranges for kindergarten is 17-21

and the class ranges for 7th grade is 25-34

here's where i prove 'a' to be the correct answer;

21-17=4

34-25=9

the ranges for 7th grade is 5 more than that of a kindergarten class making 'a' the right answer

**i know i'm not an expert but an ace, i've just been trying to become a genius, sorry :(**

good luck :)

hopefully, this helps

have a nice day !!
