Solution 11976: Performing T-Test Computations Using a TI-83 Family, TI-84 Plus Family or TI-Nspire™ Handheld in TI-84 Plus Mode.

How do I compute a T-Test using a TI-83 family, TI-84 Plus family or TI-Nspire handheld in TI-84 Plus mode?

The following example demonstrates how to perform a T-Test calculation using a TI-83 family, TI-84 Plus family or TI-Nspire handheld in TI-84 Plus mode. 

Data for this example:

{30.3, 30.5, 30.6, 31, 30.7, 30.7, 30.4, 30.9, 31}

Entering the data:

1) Press [STAT] [1] to access the STAT List Editor.
2) Input the example data into the L1 list, pressing the [ENTER] key after each entry.



3) Press [2nd] [MODE] to QUIT the STAT List Editor and return to the home screen.

Computing the T-Test:

1) Press [STAT] and scroll to the left to highlight TESTS menu.
2) Press [2] to select the T-Test function.



3) If "Data" is not selected, move the cursor to highlight Data and press [ENTER].
4) Input 30.5 for the claimed value of m0.
5) Make sure List: is set to L1. If not, move the cursor next to List: and press [2nd] [1].
6) Highlight >m0 and press [ENTER]. This means the mu (m) is greater than the alternate hypothesis (m0).



7) Scroll down to Calculate and press [ENTER]. The T-Test returns a test statistic of 2.1009.
