As mentioned before, methods of making inferences about parameters are either estimating the parameter or testing a hypothesis about the value of the parameter. In this lesson, we will introduce the concepts of hypothesis testing. Then we will discuss hypothesis testing for a population proportion. In the next Lesson, we discuss inference for the population mean.
- Explain the concepts of hypothesis testing.
- Set up hypotheses.
- Perform hypothesis testing for a population proportion using the p-value approach and the rejection region approach.
- Use a confidence interval to draw a conclusion about a two-sided test.
