Hypothesis Testing

This section deals with hypothesis testing.

In general, hypothesis testing means testing whether some claim about a characteristic of a population is believable or not based on a random sample from the population in question.

There are three subsections which correspond to the three different situations we have covered:

• Testing hypotheses when the population standard deviation $\sigma$ is known
• Testing hypotheses when the population standard deviation $\sigma$ is unknown and must be estimated from the sample
• Testing hypotheses about proportions

Each section has a link to a spreadsheet that can be used to perform the required calculations, and a detailed description of how to use it.
