Q4:M9:Illustrating Hypothesis Testing-Statistics and Probability 11
We make every day decisions in our life. Some of these are very important while others are not. In decision-making, we follow certain processes like weighing alternatives, collecting evidence and making a decision. An appropriate interpretation is form after a decision is made. We follow these steps in testing hypothesis in Statistics. Hypothesis testing is a way for you to test the results of a survey or experiment to see if you have meaningful results.
After going through this lesson, you are expected to:
1. illustrates: (a) null hypothesis; (b) alternative hypothesis; (c) level of significance; (d) rejection region; and (e) types of errors in hypothesis testing. (M11/12SP-IVa-1)
Subtasks:
1. distinguish null hypothesis from alternative hypothesis.
2. determine whether a hypothesis test is non-directional or directional.
3. determine whether a directional test is left-tailed or right-tailed
4. locate critical values under the normal curve.
5. determine critical values for the hypothesis testing; and
6. understand the concept of Type I and Type II error.
