I can not set up a 2 way table online but what they want is a collom of the information neatly laid out...

With the 9th graders in one collom and the 10th graders in the other

like this

                           9th grader   10th grader
# of students          32                      40
# of participated    32                      18

Draw this out with lines and it will be correct.

I hope this helps GOOD LUCK...this is tough math for a middle schooler.
