Consider the population of Oakton Community College students who only take classes at the Skokie campus.

A. Suppose we select three classes chosen at random on the Des Plaines campus on a random Monday in September. Would this be a representative sample of our population? Explain your answer.

B. Suppose for each student's birthdate, the birth month of each student taking classes on the Skokie campus is recorded e.g. for 02/12/86, we would record 02. Is this a parameter or a statistic? Is this variable qualitative or quantitative?

C. Explain how you could generate a sample of 8 course sections from all courses on the Skokie campus during a given semester using the stratified sampling method, given a list of all course sections. Suppose the researchers are interested in learning more about course offering times and student success.
