This lecture covers the two-sample t-test, used to compare means of two independent samples. The assumptions, hypothesis testing steps, and calculation of the test statistic are explained. An example with mouthwash usage and bacterial count is provided. The Welch test and the difference between statistical and practical significance are also discussed.
