Consider the least-squares regression line Cognition = 85.3 - 2.54 Years that predicts the score on a cognition test given the number of years playing hockey. Find the predicted cognition score for the given case. Two intervals are shown below: one is a 95% confidence interval for the mean response and the other is a 95% prediction interval for the response. Which is the 95% confidence interval for the mean response? Given a person who has played hockey for 5 years: Interval I: (28.2, 117.0) and Interval Il: (62.2, 83.0)

Given a person who has played hockey for 5 years:
Interval I: (28.2, 117.0) and Interval lI: (62.2, 83.0)
