Answer: 200 randomly selected students in the school

Step-by-step explanation:

Population refers to a total set of observation that can be made, a whole group or entire set which we desire to observe or test. While sample refers to a smaller manageble version of a population on which testing could be done. Samples should be selected randomly and should contain characteristics of the larger group.

In the case above the sample is the 200 randomly selected students in the school because because that is the selected set of people from which testing was done to draw conclusions about the whole population.
