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 variable Hipp measures brain size as the volume of the hippocampus (in ML) for each subject. Uploading the file FootballBrain is not recommended for this problem. You can find the data in the drop-down menu, as Brain Size (Football:No Concussion vs. Concussion). a. Define the parameter(s) for this question, using appropriate notation. b. Write the null and alternative hypotheses in terms of the parameter(s) above. c. Use StatKey to find the value of the relevant sample statistic. Write it using correct notation. d.
