An example of statistical inference is hypothesis testing.

Here's why:

1. Hypothesis testing: This is a statistical method that is used in making statistical decisions using experimental data. It is basically an assumption that we make about the population parameter. This method is used to test the validity of a claim that is made about the population. This is a form of inferential statistic.

2. Calculating the size of a sample: This is not an example of statistical inference. It's a part of the process of collecting data for statistical analysis, but it doesn't involve making predictions or drawing conclusions about a larger population.

3. A population mean: This is a parameter of the population, not a process of inference. Inference might be used to estimate the population mean, but the mean itself is not an example of inference.

4. Descriptive statistics: This is a branch of statistics that involves methods for organizing and summarizing information but does not involve making predictions or drawing conclusions about a larger population.

So, the correct
