Question: Extra Credit (5 points): You read the following summary paragraph about a recent study.

“A group of researchers theorize that students at Drexel University are likely to be of a lower weight than the general population of undergraduate students in the US. They selected a sample of 10 male students from Drexel University by posting a recruitment flyer at the local gym. They do not take weights of the students, but allow each student to self-report their weights. They set an alpha (?) level of .10, and, after rejecting their null hypothesis, concluded that, in fact, students at Drexel weigh less than the general population of undergraduate students.”

List all the things in this description that would lead you to believe the researchers have done something incorrectly, or that would lead you to view the results with skepticism.
