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=-1.111 b=27.579 r2=0.725904 r=-0.852 Use this to predict the number of situps a person who watches 8.5 hours of TV can do (to one decimal place)
