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.
