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=-1.145 b=20.742 r2=0.508369 r=-0.713 Use this to predict the number of situps a person who watches 2.5 hours of TV can do (to one decimal place)
