Questions: Researchers often take information gained from a small sample in order to determine how their treatment may affect the entire population.

Solution Steps

The question is asking to match terms related to statistical studies. The goal is to identify which pair of terms correctly completes the sentence about how researchers use samples and populations in their studies.

1. Understand the context: Researchers use a small group (sample) to make inferences about a larger group (population).
2. Identify the correct pair of terms that fit this context.

In statistical research, a small group of subjects is often studied to draw conclusions about a larger group. This smaller group is referred to as the \( \text{sample} \), while the larger group is known as the \( \text{population} \).

The question provides several pairs of terms. The correct pair that fits the context of using a sample to infer about a population is \( \text{sample} \) and \( \text{population} \).
