 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=-1.386 b=39.577 r²=0.724201 r=-0.851



Use this to predict the number of situps a person who watches 7 hours of TV can do (to one decimal place)
