Solution

The correct answer is "hypothesis testing". This is an example of statistical inference because it involves making an educated guess about a population parameter based on a statistic computed from a sample. The other options do not involve making inferences about a population based on sample data. A population mean is a parameter, not an inference. Descriptive statistics summarize and organize data from a sample but do not allow for inferences about the population. Calculating the size of a sample is a part of research design, not statistical inference.
