An example of statistical inference is hypothesis testing.

Here's a step-by-step explanation:

1. Statistical inference is the process of using data analysis to deduce properties of an underlying probability distribution.

2. It involves making predictions or decisions about a population based on a sample of data taken from the population in question.

3. Hypothesis testing is a method used in statistics to infer or draw conclusions about a population based on a sample of data.

4. In hypothesis testing, an initial claim about a population is made, and then evidence is collected from the sample to either support or reject the claim.

5. Therefore, hypothesis testing is an example of statistical inference because it involves making an educated guess about a population parameter based on a sample from that population.
