At UF, 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 leave Gainesville 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 ask 500 students selected at random from those coming out of the library during final exam week.Will this sample be representative of all UF students?

No, since only people at the library were used.

Yes, since it was done at random.

Yes, since the sample size is pretty large.

No, since it was done by the Student Government.
