Hypothesis T-Tests on Means, sigma unknown

In this video I show you how to perform a hypothesis test using the Traditional Method on one sample means if you don't have sigma. I use a t-table to get critical values. I show you how to use the formula to turn your sample mean into a t-value and I also show you how to find it on a TI-84 calculator. There are 3 examples of 1-sample t-tests on means, including one with data!
