MATH200Z Program — Technical Notes

Copyright © 2009–2019 by Stan Brown

Summary: This document contains the details of variable usage by the MATH200Z subprogram, and it’s probably of no interest to you unless you’re programming the TI-83/84 yourself.

The MATH200Z subprogram is called by MATH200A and MATH200b, and you’ll never run it directly. If you want to know how to use those programs, please see MATH200A Program — Basic Statistics Utilities for TI-83/84 and MATH200B Program — Extra Statistics Utilities for TI-83/84.

MATH200Z presents common dialogs for getting data and confidence levels, and validates the user’s input. The calling program sets the variable θ to tell MATH200Z what to do. This document shows what MATH200Z does with each value of θ and what variables it sets for use by the calling program.
