list editor. The TI-84 Plus has six list variables in memory,
L1 through L6, to which you
31. Press £
20 ¤ to enter a string length of 20 cm.
Press Í to calculate the predicted time of
about 0.92 seconds.
Based on the residual analysis, we would expect
the prediction of about 0.92 seconds to be within
about 0.02 seconds of the actual value.

5 to change the string length to 50
cm.
33. Press Í to calculate the predicted time of
about 1.48 seconds.
Since a string length of 50 cm exceeds the lengths
in the data set, and since residuals appear to be
increasing as string length increases, we would
expect more error with this estimate.
Note: You also can make predictions using the
table with the
TABLE SETUP settings Indpnt:Ask
and
Depend:Auto (Chapter 7).
