Two Sample T-Test (Bivariate) - Sales Training Example

This video describes how to conduct a Two-Sample T-test using a sales training scenario. In this case, we are using a two-tail example testing the question: Is there a difference between salespeople if they have taken the sales training?
Note that since this is a two-tail test, we only care about whether or not the two groups (trained or untrained) are different. We are not asking the question: Are trained salespeople selling more than untrained salespeople? (which would be a one-tail T-test.)

If you could upload the link to the datasets that you use in your videos it would be perfect?!
