2. This problem requires computer output. Your screenshot should be in a separate le with "problem2screenshot" in the name. Concussions and Brain Size. In this exercise, we test for evidence that average brain size is larger in football players who have never had a concussion {FBNoConcuss} than in football players with a history of concussions {FBConcuss}. The data are in a le in the same place as this quiz document with FootballBrain* in the title. The variable Hipp measures brain size as the volume of the hippocampus (in ,uL) for each subject. * The data file with FootballBrain in the title is a revised version of the FootballBrain dataset from Lock. It has all Control group cases removed. If you do not find that le or if it does not seem to have the characteristics described here, please email the instructor about that.) a. Define the parameterl s} for this question, using appropriate notation and words. b. Write the null and alternative hypotheses in terms of the parameterls) above, using words and symbols. c. Use StatKey to find the value of the relevant sample statistic. Use correct notation and give the value of it. d. Use StatKey to find the pvalue for your hypotheses. Include a screenshot of the randomization dotplot with tail area(s} with your quiz submission and write the p-value here
