Answer 31

I think it's the 2nd one, " He did not use a random sample, and he tried to show cause and effect with an observational study." Since he simply asked his friends, without gathering any real tangible or reliable information. Plus, he already knew the subjects being asked, so they could've just told him what he wanted to hear...
