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:
Use this to predict the number of situps a person who watches 0.5 hours of TV can do (to one decimal place)
The results of the regression were:
y=ax+b a=-0.678 b=33.358 r2=0.467856 r=-0.684
Use this to predict the number of situps a person who watches 0.5 hours of TV can do (to one decimal place)
