A researcher predicts that fans who played high school basketball will form better brackets (i.e., have more correct picks) than fans that did not play high school basketball. The researcher recruits ten fans, records whether they played high school basketball, and then has them complete a bracket for the first round of the tournament. She finds the following number of correct picks: Played high school basketball Didn't play high school basketball 12 6 8 10 4 14 12 14 12 8
