Hypothesis Testing for Means

In this class, we introduce hypothesis testing for means. In the video, below, I go through the notion of the Research and Null Hypothesis, how to establish an Alpha level as a cutoff point, and what it looks like under the normal curve. We furthermore go through how to get the Z-obtained value, for means. The final part of the presentation discusses when to Reject the Null Hypothesis, what that means, and how to interpret the result.

The formula we use to calculate the Z-obtained value is:

Watch the whole video and take notes to consult in our synchronous part of the class.
