Textbook Question
Chapter 11.1, Problem 20E
A researcher at the Medical College of Virginia conducted a study of 60 randomly selected male soccer players and concluded that frequently “heading” the ball in soccer lowers players’ IQs (USA TODAY, August 14, 1995). The soccer players were divided into two groups, based on whether they averaged 10 or more headers per game.
- a. Do these data support the researcher’s conclusion? Test the relevant hypotheses using α = 0.05.
- b. Can you conclude that heading the ball causes lower IQ?
