Question 1127760: ***Corrected from previous request ***
In need of assistance please, as I am completely lost.
I was hoping to receive help understanding the following question:
A regression was run to determine whether 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 are given below. Use this to predict the number of sit-ups a person who watches 11 hours of TV can do.
y=ax+b
a=-1.341
b=32.234
r=-0.896
What is really throwing me off is where "r" comes into play.
I am not simply seeking an answer, instead I am asking for your knowledge on how to understand this type of equation, and how to solve something such as this.
Thank you for your time! Found 2 solutions by addingup, MathTherapy:Answer by addingup(3677) (Show Source):
You can put this solution on YOUR website! y' = 1.341 + 32.234
y' at x = 11 is
y' = 1.341(11) + 32.234
= 46.985, you can round it off to 47
You can put this solution on YOUR website!

Thank you for your time!
I gave you the answer in your previous post explaining why "r" was given, and what you need to do in order to predict "y".
Why are you re-posting the problem?
