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

    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 -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?
