Answer to Question 1

FALSE

Answer to Question 2

We might be interested in determining these expenditures for all students currently enrolled in a four-year institution of higher learning in the United States. We would want to collect a random sample such that each of the thousands of students in the population is equally likely to be selected. We would not just want to study the expenditures of students at a private college, as their expenditures may be quite different from those of students in public colleges.
