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=-1.396 b=28.536 r²=0.853776 r=-0.924 Use this to predict the number of situps a person who watches 1 hours of TV can do (to one decimal place)
