Z Tests for One Mean: Introduction
An introduction to Z tests for a population mean mu. These tests are appropriate when sampling from a normally distributed population where sigma is known. I discuss the hypotheses and the underlying logic, and work through an example. I do not discuss the rejection region or p-value in an in-depth way in this video -- I discuss them in other videos, and provide links at the end of this one.
