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

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. 26 b=33 . 499 r2=0. 614656 r=-0 . 784 Use this to predict the number of situps a person who watches 6.5 hours of TV can do (to one decimal place)
