In this video, I explain the T-Test as an important method of hypothesis testing in Probability and Statistics. The lecture covers the t-test for one mean and the t-test for two means, including null and alternative hypotheses, and one-tailed and two-tailed tests. This session is especially useful when population variance is unknown and sample sizes are small, helping students and beginners build a strong conceptual understanding.
