Years. 1Singh R, et al., "Relationship of Collegiate Football Experience and Concussion with Hippocampal Volume and Cognitive Outcomes". JAMA, 311(18), 2014. Data values are estimated from information in the paper. (a) Predict the cognitive percentile for someone who has played football for 8 years and for someone who has played football for 14 years. Enter the exact answers. The cognitive percentile for someone who has played football for 8 years is The cognitive percentile for someone who has played football for 14 years is eTextbook and Media Hint (b) Interpret the slope in terms of football and cognitive percentile. For every additional unit that cognitive perc entile goes up, the predicted number of years of playing football goes down 3.34. O For every additional year playing football, the predicted cognitive percentile goes down 3.34. O People who play more years of football score lower on cognitive percentile. O For every 3.34 years of playing football, cognitive percentile is 102. eTextbook and Media Hint (c) All the participants had played between 7 and 18 years of football.
