Question 1198499: 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. Answer by ikleyn(52797) (Show Source):
