Entering the Values for Arguments
Inferential stat editors require a value for every argument. If you do not
know what a particular argument symbol represents, see the
Statistics Input Descriptions tables
When you enter values in any inferential stat editor, the
TI-83 Plus
stores
them in memory so that you can run many tests or intervals without
having to reenter every value.
