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=-0.71
b=29.327
r2=0.923521
r=-0.961
Use this to predict the number of situps a person who watches 7 hours of TV can do (to one decimal place)
