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=-0.678
b=30.1
r2=0.4096
r=-0.64
Use this to predict the number of situps a person who watches 9.5 hours of TV can do (to one decimal place)
