Answer:
This process is known as stratified random probability sampling.
Explanation:
Probability sampling is based in the fact that every member of the studied group has an equal probability of being chosen as a subject in the study and every member can be representative of such group. In probabilty sampling, the subjects of the sample are chosen randomly, but there are also different types of probability sampling.
Stratified random probability sampling involves dividing the population into groups and then choosing randomly within each group. Linda has divided her subjects into the ones that eat at the restaurant for breakfast, lunch or dinner, then she plans to choose randomly from those three groups. Therefore, she is using the process known as stratified random sampling.

While other non students don't have to really worry as much as these things because they aren't in school anymore.
