13. Judging from the questions, I don't think the person above ^ is right and I'm not willing to try them out because I already failed my last test from stuff like that. However, I could be wrong. But I'm pretty sure the answer to #3 is D, not B because it would make more sense to have a random sample from the entire movie complex??? I don't trust it.
