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=-1.072
b=22.446
r2=0.383161
r=-0.619
Assume the correlation is significant, and use this to predict the number of situps a person who watches 2.5 hours of TV can do (to one decimal place)
