This statistics video explains how to use the p-value to solve problems associated with hypothesis testing. When the p-value is less than alpha, you should reject the null hypothesis and vice versa. This video discusses when you should use a one tailed test compared to a two tailed test. It contains two example problems that illustrates how to use the p-value method to determine if you should reject or not reject the null hypothesis.
