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=-0.827 b=27.026 r2=0.683929 r=-0.827 Use this to predict the number of situps a person who watches 12 hours of TV can do (to one decimal place)___________
