Statistics 101: Single Sample Hypothesis z-test - Part 2 • Part 1: Conceptual Background • Part 2: Example Problems • Part 3: The Alpha Effect and p-values • In Part 2 of this video, we walk through two example problems involving single sample hypothesis tests including graphical representations of the hypothesis distribution. For this type of test, we are comparing a sample mean to a hypothesized population mean. We examine the rejection region, nonrejection region, and the critical values that separate them. Finally, we learn how our selection of alpha (significance level) influences our rejection/nonrejection regions and Type I and Type II errors.
