    Question

    A student investigated whether walking and puzzling (both expressed in number of minutes per day) have an effect on cognitive functioning in the elderly. She found the regression equation below: cognitietest=5+0.5wandelen+0.3puzzelen+ecognitietest = 5+0.5wandelen+0.3puzzelen+e. Given are two elderly people, one of whom walks every day for 60 minutes but does not do puzzles, and the other who does puzzles every day for 120 minutes but does not walk. What is the expected difference in score on the cognition test between these two elderly people?
