A regression was run to determine if there is a relationship between hours of TV watched per day (x) and number of situps a person can do (y). The results of the regression were: y=ax+b a=-0.856 b=31.334 ²-0.405769 r=-0.637 Use this to predict the number of situps a person who watches 3.5 hours of TV can do (to one decimal place)
