Question
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=-1.003
b=21.314
r2=0.857476
r=-0.926
Use this to predict the number of sit-ups a person who watches 9 hour(s) of TV can do, and please round your answer to a whole number. __?__
