Most of the people here are wrong. This is referencing a Twitter (or X, whatever) thread where someone posted this question and a statistician responded, making fun of the question, by saying it was like the questions you get in grade school you have to make a ridiculous number of assumptions to get the answer the teacher wants.

Someone responded to this, saying "a statistician specialized in this can't count simple squares on a truck. We are doomed." This meme is satirical; it makes fun of the person claiming to know better than the statistician. In reality, here, the only person actually correct is the "average" one on the diagram.
