LESSON: Step Five & Six of Hypothesis Testing

Step 5 & 6 for a Lower Tail Test

We're wrapping up hypothesis testing by learning the last two steps in the process. Step 5 is calculating the critical values. Step 6 is determining, based on the critical values, if we reject or fail to reject the null hypothesis.

In this video, I will go over the example of a lower tail test (Sam's bowling average).

Step 5 & 6 for an Upper Tail Test

In this video I will wrap up the example of Mike's claim that the average house price in Castle Hill is above $500,000. This is an upper tail hypothesis test.

Step 5 & 6 for a Two Tail Test

In this video I will wrap up the example of Youtube's claim that the average age of users is 25. This is a two tail hypothesis test.
