Statistics and Probability Module: Drawing Conclusion About Population Mean Based on Test Statistic Value and Critical Region

This Self-Learning Module (SLM) is prepared so that you, our dear learners, can continue your studies and learn while at home. Activities, questions, directions, exercises, and discussions are carefully stated for you to understand each lesson.

Each SLM is composed of different parts. Each part shall guide you step-by-step as you discover and understand the lesson prepared for you.

Pre-tests are provided to measure your prior knowledge on lessons in each SLM. This will tell you if you need to proceed on completing this module or if you need to ask your facilitator or your teacher’s assistance for better understanding of the lesson. At the end of each module, you need to answer the post-test to self-check your learning. Answer keys are provided for each activity and test. We trust that you will be honest in using these.

Please use this module with care. Do not put unnecessary marks on any part of this SLM. Use a separate sheet of paper in answering the exercises and tests. And read the instructions carefully before performing each task.

So far, you’ve already learned how to formulate null and alternative hypotheses, identify appropriate test statistic, look for critical values, identify the critical region, and compute for the value of the test statistic.

In this module, you will learn how to interpret the result based on the computed value of t-test and z-test. Perform each activity independently. If you find any difficulty in answering the exercises, you may consult your peers or ask the assistance of your teacher.

After going through this module, you are expected to:

1. recall and apply steps in hypothesis testing; and

2. draw conclusion about the population mean based on the test statistic value and the rejection region.

Before you proceed to the lesson, make sure to answer first the questions on the next page (What I Know).
