C The population is all classrooms in the high school; the sample is the 10 classrooms selected.
how
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.
The correct answer is C.
Explanation: In this scenario, the population refers to the entire group that the researcher is interested in studying, which is all the classrooms in the high school. The sample, on the other hand, refers to a smaller subset of the population that is actually observed or tested, which in this case is the randomly selected group of 10 classrooms. Therefore, option C correctly identifies the population as all classrooms in the high school and the sample as the 10 classrooms selected.
