.
A regression analysis was performed 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=-1.386
b=23.093
r2=0.571536
r=-0.756
Use this to predict the number of sit ups a person who watches 9.5 hours of TV can do, and please round your answer to a whole number.
