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=-1.226
b=33.622
r²-0.4489
r=-0.67
Use this to predict the number of situps a person who watches 3 hours of TV can do (to one decimal place)
