C. Sample, because the collection of ages of one person per row is a subset of all people in the cinema.
D. Population, because it is a subset of all people in the cinema

Answer 1

The correct answer is C. Sample, because the ages of one person per row in a cinema represent a subset of all the people in the cinema, which is a typical approach for surveys and research to gather information.

Step-by-step explanation:

To determine whether the data set is a population or a sample, we need to understand the context. In this case, the ages of one person per row in a cinema are being collected. The question is whether this dataset is the entire group of interest or just a part of it.

Considering that a population is all the subjects that are being studied, and a sample is a subset of the population selected for observation and analysis, the correct answer is C. Sample, because the collection of ages of one person per row is a subset of all people in the cinema.

This situation aligns with the concept of acquiring information through samples to infer about an entire population.

Similar to how surveys and medical research often work with a subset of the entire group, the ages collected here represent only a portion of all views at the cinema.
