Statistics 101: Single Sample Hypothesis Z-test Concepts

Statistics 101: Single Sample Hypothesis z-test - Part 1
Part 1: Conceptual Background
Part 2: Example Problems
Part 3: The Alpha Effect and p-values
In Part 1 of this video, we discuss the basics of single sample hypothesis testing when we know or are given the population standard deviation. 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 to compute the z-statistic. Enjoy!
