HOW TO FIND MATCHED PAIRS T PROCEDURES WITH TI83 CALCULATOR

Steps	Key Sequence	Screens
1. Enter sample1 data into list, L1
2. Enter sample2 data into list, L2
3. Enter differences into list, L3	2nd, then 1 (for L1)
	–, then 2nd, then 2 (for L2)
	Press STO, then 2nd, then 3 (for L3)
	ENTER
3. Perform one sample t test using Data with μ0 = 0, List, L3, and appropriate test
In this case, the test was Ha: μ ≠ 0; the one–sample t statistic is –2.904; the p–value is 0.0078; the sample mean is –13.32; the sample standard deviation is 22.936 and the sample size is 25.
