Answer #1

Answer: The study depicts an observational study, because we do not conduct any experiment for the collection of the data. We know that the observational study is the study where researcher simply collect the data by observations only and do not apply any treatment. An experimental study is the study where researcher conducts an experiment and researcher apply different treatments to subjects for finding the effects.
