7-103.
At a family reunion, each family member recorded his or her age and height.
Fully describe the association.
As age increases, so does height.
There is a moderate, positive, linear association. Are there any outliers?
Copy the scatterplot and draw the trend line. Does your
-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-intercept?
