Here you'll answer questions about how to discern the best type of test to run in an example scenario and what it means when the p-value is less than the significance α.

## Quiz & Worksheet Goals

Take this quiz to see how well you understand:

• What cannot be done with a null hypothesis
• What kind of test is being run in an example scenario
• The type of distribution used if the sample size is small and the population standard deviation is unknown
