Experience 12 - Hypothesis Testing (Part 2)

Hypothesis Testing: Full Procedure

Why

This important procedure is the industry standard technique for scientifically supporting and refuting claims about population means and proportions. You will find that something similar to these tests is used to determine if drugs are safe, new methods are better, or if people's opinions have changed. 

Learning Objectives:

• Know the general process of hypothesis testing using p-values.

Performance Criteria

• The learner will translate written scenarios and small data sets into corresponding hypothesis tests and use the complete procedure to test claims.
