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=-1.346 b=24.753 r2=0.6724 r=-0.82 Use this to predict the number of situps a person who watches 4 hours of TV can do (to one decimal place)
