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=-0.838 b=28.783 p2=0.784996 r=-0.886 Use this to predict the number of sit ups a person who watches 1 hours of TV can do, and please round your answer to a whole number.

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

\[ y = ax + b \]
- \( a = -0.838 \)
- \( b = 28.783 \)
- \( r^2 = 0.784996 \)
- \( r = -0.886 \)

Use this to predict the number of sit-ups a person who watches 1 hour of TV can do, and please round your answer to a whole number.
