Each set of data has 100 percentiles.

Indicate whether the statement is true or false

Question 2

Suppose you were interested in determining the average monthly expenditures of college students on DVDs.

How would you define the population for this problem? How would you obtain sample data for this study? Why would you want to ensure that you survey a random sample of college students?

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.
