Display the scatter diagram for the data by pressing WINDOW and setting Xmin = 10, Xmax = 30, Xscl = 5, Ymin = 15, Ymax = 40, and Yscl = 5. Press Y= CL to clear any previously entered expressions. Press GRAPH to view the scatter diagram.

To view the overlay of the regression line and the scatter diagram, press Y= VARS , touch H STAT, press ENTER , touch B REGEQN, double touch

1 RegEqn, and press GRAPH . The following overlay will be displayed.

For Discussion

You and your students can discuss:

1.In what pattern would the data points lie to form a coefficient

of correlation of zero?
2. Engage the trace and pressing	▼ or ▼ and using the

regression line to make a prediction.
