![]() So, 95% of the time, the true difference in means will be different from 0. ![]() T test exampleFrom the output table, we can see that the difference in means for our sample data is −4.084 (1.456 − 5.540), and the confidence interval shows that the true difference in means is between −3.836 and −4.331. This can be changed from 95% if you want a larger or smaller interval, but 95% is very commonly used. This is the range of numbers within which the true difference in means will be 95% of the time. In this test, the H a is that the difference is not 0.
