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=-1.244
b=35.185
r2=0.974169
r=-0.987
Use this to predict the number of situps a person who
watches 5.5 hours of TV can do (to one decimal place)
