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=-0.873
b=26.391
r2=0.919681
r=-0.959 Use this to predict the number of situps a person who watches 11.5 hours of TV can do (to one decimal place)
