Question

100%

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=-1.315

b=25.889

r²=0.729316

r=-0.854

Use this to predict the number of situps a person who watches 5 hours of TV can do (to one decimal place) ?
