McAllister et al. (2012) compared varsity football and hockey players with varsity athletes from non-contact sports to determine whether exposure to head impacts during one season have an effect on cognitive performance. In the study, tests of new learning performance were significantly poorer for the contact sport athletes compared to the non-contact sport athletes. The following presents data similar to the results obtained in the study: Contact Athlete: 7, 4, 9, 5, 6, 7, 10, 8 Non-Contact Athlete: 10, 8, 7, 9, 13, 7, 11, 12 Are the test scores significantly lower for the contact sport athletes than for the non-contact athletes? State the null and research (alternative) hypotheses in words and using symbols. Conduct the appropriate hypothesis test with = .05 and state your conclusion in terms of this problem. Remember to use the 4 steps of hypothesis testing and include the SPSS output as evidence for calculations. Make sure to write APA style conclusions as shown in lecture & example videos.
