Program Instructions:
1.
Key in the program and press
fCLEARH.
2.
For each input pair of values, key in the y-value and press
\(³), key in the
corresponding x- value and press
t.
3.
After all data pairs are input, press
g(006t to obtain the correlation
coefficient (between ln y and x).
4.
Press
t to obtain A.
5.
Press
t to obtain B.
6.
Press
t to obtain the effective growth rate as a decimal.
7.
RPN: To make a y-estimate, key in the x-value and press t. For subsequent
estimates, key in the x-value and press
g(025t.
7.
ALG: To make a y-estimate, key in the x-value and press t. For subsequent
estimates, key in the x-value and press
g(028t.
8.
For a different set of data, press
fCLEARH and go to step 2.
