The owner of a large office building is considering expanding the buildings' daycare center, which all employees of the the building can use and wants to know what the employees think of this idea. A survey is taken by giving a questionnaire to every parent/guardian of the children in the daycare center asking if the daycare should be expanded.

What is the population?
What is the sample?

Population = all employees

Sample = parents using daycare

To understand the population and sample in this scenario, let's break it down:

Population: The population is the entire group of interest that we want to draw conclusions about. In this case, the population is all the employees of the large office building, as the owner wants to know what they think about expanding the daycare center.

Sample: A sample is a subset of the population that is selected for analysis. It is representative of the larger population. In this case, the sample refers to the parents or guardians of the children in the daycare center who are given the questionnaire about expanding the daycare. The sample represents the population of employees.

Therefore, the population is all the employees of the office building, and the sample is the parents or guardians of children in the daycare center.
