Read the problem carefully. Then read each choice and see if it makes sense.

Look at a. The sample is the percentage of students who ride the bus. Does that make sense? There's 200 people in the sample and only 38% said they ride the bus...

i think its b....

aripotta · Answer

Yes, I'd go with b as well. Seeing as it's an after school activity, most people who ride the bus probably wouldn't even be there, since they, more than likely, take the bus home too
