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:ŷ=a+bx a=38.98 b=-1.245 r²=0.802816 r=-0.896



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