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= -0.682

b=21.214

r²=0.822649

r= -0.907

Use this to predict the number of situps a person who watches 9 hours of TV can do (to one decimal place)
