A regression was run to determine if there is a relationship between hours of TV watched...

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=-0.609
b=35.322
r²=0.481636
r=-0.694

Use this to predict the number of situps a person who watches 7.5 hours of TV can do (to one decimal place)
