Comes from a class I took senior year of HS, and I didn't find it online so hopefully this isn't a repeat.
A renowned psychologist is touring High Schools all over the country with her latest finding.
Theory: There is a really popular student in each class in the entire school, such that if that student drinks, then everyone in that class drinks.
Is this just due to a small sample size, or is this always true, sometimes true, or never true? And please prove why this is the case.
Please enclose your answer in a spoiler using this ">!"
Also please feel free to suggest tags. I am not too familiar with the tags here
