The population of interest

This is the total number of students in the college

Hence, the population of interest is the students in the college

The parameter of interest

Hence, the parameter of interest is the proportion of college students that work part-time

The sample in the study

This is the students that were randomly surveyed

Hence, the sample in the study is the 2,512 students that were randomly surveyed
