A study was done that measured the association between people's vertical jump ability (how high they can jump from a stationary position) and how much they can leg press. The resulting correlation was $0.98$. Which of the following statements are true?
I. If you leg press more than someone else, then you will have a higher vertical jump than him or her.
II. If you leg press less than someone else, you will have a lower vertical jump than him or her.
III. There is a very strong positive linear association between leg press ability and vertical jump.
