Example 2:
Repeat example 1 (using the same data) for logarithmic, exponential, and power
curve fits. The table below gives you the starting execution label and the results (the
correlation and regression coefficients and the x– and y– estimates) for each type
of curve. You will need to reenter the data values each time you run the program
for a different curve fit.
