The TI-92 program chaos below examines the dynamical system
p(1) = 50
p(n + 1) = 4.0 * (1 - 0.001 * p(n)) + p(n)
and counts how many of the first 400 terms in this sequence fall between 0 and 500. If the sequence is truly "random" or "chaotic" then we would expect roughly one-half of the terms to be between 0 and 500. You can enter this program from the keyboard of your TI-92 or if your workstation has the TI-Graph Link cable and software you can download it from the computer to your TI-92. Once the prigram is in your TI-92 run it by typing chaos() and then pressing ENTER in your home screen.
