Answer 3

The population refers to the entire group of classrooms at the high school, while the sample is the smaller group of 10 classrooms that were selected for the air quality tests. Since the health inspector is only conducting tests on classrooms at the high school, the population is limited to just that school. Therefore, option C is the correct answer.
