7-103.

At a family reunion, each family member recorded his or her age and height.

1. Fully describe the association.

As age increases, so does height.

There is a moderate, positive, linear association. Are there any outliers?

2. Copy the scatterplot and draw the trend line.  Does your $y$-intercept make sense in this problem situation?

A child of 0 years should still have a little positive height.
What does this mean about the $y$-intercept?
