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=a+bx
b=-1.067
a=37.761
r2=0.430336
r=-0.656
Use this to predict the number of situps a person who watches 6 hours of TV can do.

Round to one decimal place.
