Statistics and Probability Module: Drawing Conclusions About Population Proportion Based on Test Statistic Value and Rejection 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 teacherâ€™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.

In conducting a study, the last part of the process is drawing conclusions and it should be done correctly and carefully. In doing so, you need to learn how to consider necessary data as your basis and follow different steps.

On the previous lessons, you were already taught how to compute test statistic concerning population proportions as well as how to determine the rejection or non rejection region by using an illustration on a curve.

After going through this module, you are expected to:

1. compute for the test statistic of population proportion;

2. differentiate critical value approach from p-value approach of hypothesis testing; and draw conclusions on population proportions based on the test statistic and the rejection region.
