Which of the following may constitute a population? (choose all that are correct.)

A. all rats in New York.

B. all nurses in a hospital.

C. all skyscrapers in Chicago.

D. all brown-haired people in Oslo.

A very broad definition of population would include all of those. A more narrow definition would eliminate the skyscrapers because they are not animate.

What does your text say about population?

it doesn't say anything, im doing it online and there was nothing in the notes about it, but i do know the title of the section is called "samples and Population"

All nurses in hospital

That's okay. In general, a population refers to a group of individuals or objects that share one or more characteristics of interest. These individuals or objects can be anything from people, animals, plants, bacteria, buildings, etc. A subset of the population is called a sample. Scientists use samples to make inferences or draw conclusions about the entire population.

So, based on this definition, options A, B, and D could all be considered populations. Option C, however, would not be considered a population because skyscrapers are not individuals or objects that share a characteristic of interest.

To determine which options may constitute a population, let's understand what a population is. In statistics, a population refers to the entire group of individuals, objects, or events that you want to study or collect data from.

Let's assess the given options:

A. "All rats in New York": This option refers to a specific group of individuals (rats) located in a defined area (New York). Therefore, it represents a population.

B. "All nurses in a hospital": This option refers to a specific group of individuals (nurses) within a defined setting (hospital). It represents a population.

C. "All skyscrapers in Chicago": This option refers to a specific group of objects (skyscrapers) located in a defined area (Chicago). Although not individuals, objects can also form a population. Hence, it represents a population.

D. "All brown-haired people in Oslo": This option refers to a specific attribute (brown-haired) of individuals (people) within a defined area (Oslo). It represents a population.

Therefore, options A, B, C, and D all represent populations.
