TI-83 Plus Inferential Statistics and Distributions 390
Selecting Data or Stats
Most inferential stat editors prompt you to select one of two types of
input. (1.PropZInt and 2.PropZTest, 1.PropZInt and 2.PropZInt, c2.Test, and
LinRegTTest do not.)
• Select Data to enter the data lists as input.
• Select Stats to enter summary statistics, such as þ, Sx, and n, as
input.
To select Data or Stats, move the cursor to either Data or Stats, and then
press Í.
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 Inferential
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.
