Final answer:
The correct answer is option A because it describes a complete set of data for all homes in the town, which constitutes a population in statistical terms.
Step-by-step explanation:
The correct answer is option A. When we collect data regarding the number of floors in each home in a town, and we include every home within that town, we are dealing with a population. A population, in statistical terms, refers to the complete set of items or events that we are interested in studying, which in this case is every home in the specified town. This differs from a sample, which would only include a subset of those homes to represent the larger group.
The data set of the number of floors in each home in a town is a population. It represents the collection of the number of floors for all homes in the town. Since it includes data for all the homes in the town, it is considered a population rather than a sample.
