It's a simple application, really. All it does is take input from the user in the form of a real number between 0 and 5, and output the percentile of that number from the cumulative normal distribution. I wrote this because of all the (home)work I do with a table of this function. Linear interpolation is a good exercise, but it's time-consuming for bizarre Z-scores and detracts from the main point of many problems. It handles input up to 5, and the output is shown to 6 decimal places (though the accuracy is actually at least 8).
Written on an SE with a 40MHz 68030 processor using System 7.0.1. It worked fine on an LC and SE/30. If you run this on another machine or with a different version of the system, let me know! Please email me at jstruby@unlinfo.unl.edu with any comments, suggestions or bug reports. If email bounces, I can be written at 7321 Belleview, Kansas City, MO, 64114, USA.

DISCLAIMER #2: Students, don't rely on this for your probability and statistics courses. You should learn and use the method of interpolation from the tables given in your coursework before using this program, and use this later for more accuracy.
