[example continued…] A researcher is interested in understanding the online shopping habits of college students in the US. To answer this question, the researcher conducts a survey of 200 randomly selected college students from across the US. Of these 200 students, 138 of them (69%) reported that they regularly shop online. The entire group of college students in the US is an example of a _________.
