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=a+bx b=-1.276 a=24.302 r2=0.779689 r=-0.883 Use this to predict the number of situps a person who watches 3 hours of TV can do.
