Problem: More sampling on campus. You would like to start a club for psychology majors on campus, and you are interested in finding out what proportion of psychology majors would join. The dues would be $35 and used to pay for speakers to come to campus. You ask 5 psychology majors from your senior psychology honors seminar whether they would be interested in joining this club and find that 4 of the 5 students questioned are interested.
Required:
1. Is this sampling method biased, and, if so, what is the likely direction of bias?
