Hypothesis Testing

Explore the fundamentals of hypothesis testing in this comprehensive video series. Learn about rejection regions, p-values, Type I and Type II errors, power calculations, and statistical significance. Dive into Z tests and t tests for one mean, including their assumptions and applications. Understand the relationship between confidence intervals and hypothesis tests, and investigate the factors affecting test power. Gain practical experience through examples and learn how to assess the normality assumption in t tests.
