Question 2.Based on the information provided below, identify the who (cases), the what (variables), and the type of variable for each variable you identify.

One of the reasons that the Monitoring the Future (MTF) project was started was "to study changes in the beliefs, attitudes, and behavior of young people in the United States." Data were collected from 8th, 10th, and 12th graders annually. To obtain a representative sample of U.S. students, surveys were given to a randomly selected group of students. Three of the questions 12^th graders were asked was how many alcoholic beverages they drank the past month, the number of cigarettes they had smoked in the past month, and whether or not they had smoked marijuana in the past month.
