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=-1.383

b=24.599

r²=0.962361

r=-0.981



Use this to predict the number of situps a person who watches 5.5 hours of TV can do (to one decimal place)
