Question

How do I use this to predict the number of situps a person who watches 7.5 hours of TV can do (to one decimal place)

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=-1.112 b=38.481 r²-0.904401 r=-0.951 Use this to predict the number of situps a person who watches 7.5 hours of TV can do (to one decimal place) Question Help: Message instructor
