Question: 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

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=-1.12 b=30.174 r2=0.889249 r=-0.943

Use this to predict the number of situps a person who watches 12 hours of TV can do (round to one decimal place)
