Calculates regression
coefficient B.
Calculates regression
coefficient M.
Prompts for hypotheti
cal x-value.
Stores 37 in X and cal
culates y.
Stores 101 in Y and
calculates x.
Example 2. Repeat example 1 (using the same data) for logarithmic,
exponential and power curve fits. The table below gives you the start
ing 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.
