A regression was run to determine if there is a relationship between hours of TV watched per day (x) and number of sit-ups a person can do (y).

The results of the regression were:

y=ax+b
a=-0.985
b=39.064
r2=0.6241
r=-0.79

Use this to predict the number of sit-ups a person who watches 10.5 hours of TV can do (to one decimal place)
