Question

An investigation was carried out to study possible consequences of the high incidence of head injuries among soccer players. Three groups of college students (soccer athletes, nonsoccer athletes, and a control group consisting of students who did not participate in intercollegiate sports) were considered in the study. The following table gives information on scores from the Hopkins Verbal Learning Test (which measures immediate memory recall). In addition = 30.0391.

	Soccer Athletes	Nonsoccer Athletes	Control
Sample size	87	96	52
Sample mean score	30.90	29.54	29.52
Sample standard deviation	3.93	5.34	3.98

Suppose that it is reasonable to regard these three samples as random samples from the three student populations of interest.

Is there sufficient evidence to conclude that the means for Hopkins score are not the same for the three student populations? Use

? = 0.05.

(Round your answer to two decimal places.)
