1. Key in the program and press CLEAR .
2. For each input pair of values, key in the y-value and press , key
in the corresponding x-value and press .
3. After all data pairs are input, press 06 to obtain the
correlation coefficient (between ln y and x).
4. Press to obtain A.
5. Press to obtain B.
6. Press to obtain the effective growth rate as a decimal.
7. To make a y-estimate, key in the x-value and press . For subsequent
estimates, key in the x-value and press 25 .
8. For a different set of data, press CLEAR and go to step 2.
