How to do a paired t test on ti 84

The following example demonstrates how to perform a T-Test calculation.

A paired samples t-test is used to compare the means of two samples when each observation in one sample can be paired with an observation in the other sample. This tutorial explains how to conduct a paired t-test on a TI calculator. Researchers want to know if a new fuel treatment leads to a change in the average mpg of a certain car. To test this, they conduct an experiment in which they measure the mpg of 11 cars with and without the fuel treatment. Since each car receives the treatment, we can conduct a paired t-test in which each car is paired with itself to determine if there is a difference in average mpg with and without the fuel treatment. Perform the following steps to conduct a paired t-test on a TI calculator. First, we will input the data values for both samples.
