 Look at the attached table and record the ages in the Y column.
 How well were you able to estimate the ages of these famous people?
To help answer this question, make a scatterplot with your estimate
of the age on the horizontal axis and the actual age on the vertical
axis.
 Where will a point lie if you estimate it correctly? Draw in the
line that represents estimates that are 100% accurate. What is the
equation of this line?
 What does it mean if a point is above the line?
