Identify the population being studied and the sample chosen for the following scenario: The midterm exam scores of 5 out of the 22 students in your economics class.

Answer

In statistics, the 'population' refers to the entire group that is the focus of a study, while a 'sample' is a subset of individuals selected from that population to represent the whole. In this specific scenario, the group under consideration is 'your economics class,' which consists of a total of 22 students. Therefore, the population is 'All students in your economics class.' From this total group, a smaller subset is chosen for observation, which is the 5 students whose midterm scores were recorded. Thus, the sample is '5 out of the 22 students in your economics class.' Matching these definitions to the given options, the correct choice is the second one: Population: All students in your economics class; Sample: 5 out of the 22 students in your economics class.
