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 can do (y).
The results of the regression were:
y=ax+b
a=-0.816
b=24.08
r2-0.494209
r=-0.703
Use this to predict the number of situps a person who watches 10.5 hours of TV can do (to one decimal
place)
