This program asks the user to input the two correlations, the sample sizes and the desired confidence interval.  After pressing calculate, the program shows the lower and upper limits of the confidence interval and the results of a z test that tests the null hypothesis that the difference between the two correlations is zero.  The example below shows how the dialog box looks after the data have been entered and the Calculate button is pressed.
