there are always a few days between the end of classes and the beginning of final exams. These days are meant as a study period, but some students would prefer to take the exams as soon as possible, to have a longer vacation - in fact, some students even go out of town during those days as a mini-vacation. To see if the student body supports abolishing "dead week", the Student Government decides to conduct a survey. They place an ad in the student newspaper, asking students to vote. After the votes are in, they randomly select half of them to draw their conclusions. Will this sample be representative of all students on campus?

*No, since this is an example of voluntary response sample.

*Yes, since it was done at random.

*Yes, since anyone (student or not) could participate. *No, since it was done by the student newspaper
