A regression analysis was performed to determine if there is a relationship between hours of TV watched per day (xx) and number of sit ups a person can do (yy). The results of the regression were:

y=ax+b a=-0.786 b=37.449 r²=0.579121 r=-0.761

Use this to predict the number of sit ups a person who watches 1.5 hours of TV can do, and please round your answer to a whole number.
