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=-0.712 b=37.331 r2=0.817216 r=-0.904 Use this to predict the number of situps a person who watches 1.5 hours of TV can do (to one decimal place) 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=-1.356 b=33.84 r2=0.748225 r=-0.865 Use this to predict the number of situps a person who watches 13 hours of TV can do (to one decimal place) A regression analysis was performed to determine if there is a relationship between hours of TV watched per day ( x x ) and number of sit ups a person can do ( y y ).
