Sample
Sample
To answer this question, we need to understand the concepts of population and sample in the context of statistical analysis.
A population refers to the entire group of individuals, objects, or events that we want to draw conclusions about. In this case, the population consists of all the light bulbs from the large group.
A sample, on the other hand, is a smaller subset or portion of the population. It is selected from the population and is representative of the characteristics of the entire population. The purpose of taking a sample is to make inferences or draw conclusions about the population based on the sample data.
Given this information, the correct answer is D. Sample. When we test a small number of light bulbs from a large group, the small group is referred to as a sample.
