QUESTION 9 3 points Save FootballBrain (continued): Suppose a student in MATH 231 used the data available and StatKey to construct a 94% confidence interval for NoConcuss concuss . She correctly found that confidence interval to be (-2,28), with endpoints rounded to the nearest whole numbers. Which of the following is the BEST (most informative and accurate) interpretation for that confidence interval? We are 94% confident that the difference between average cognition scores for football players with or without a history of concussion is somewhere between-2 points and 28 points. We are confident that 94% of football players without concussion history will score between 2 and 28 points higher than the average football player with a history of concussions We are 94% confident that the true average cognition score for football players without a history of concussion is somewhere between 2 points lower and 28 points higher than football players with concussion history We are 94% confident that the true average cognition score for football players with a history of concussion is somewhere between 2 points lower and 28 points higher than football players without concussion history
