Create a scatterplot and LSRL on your calculator and sketch them. What is the
equation of the LSRL?
When entering the data in her calculator, Amy accidentally entered (144, 10.7)
for the first data point. Make this change to your data and sketch the new point
and new LSRL in a different color. Will Amy's predictions for the field of view
be too large or too small?
