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:ŷ=ax+b a=-1.108 b=21.055 r²=0.81 r=-0.9



Use this to predict the number of situps a person who watches 6 hours of TV can do (to one decimal place)
