A regression was run to determine if there is a relationship between hours of TV watched per day (x

x

) and number of situps a person can do (y

y

).

The results of the regression were:

y=ax+b a=-1.183 b=22.118 r2=0.719104 r=-0.848 

Use this to predict the number of situps a person who watches 2 hour(s) of TV can do, and please round your answer to a whole number.
