Question: Imagine that you have been hired by the Psychology Department at your school to administer a survey to psychology majors about their experiences in the department. You have been asked to randomly select 60 majors from the overall pool of 300. You are working on this project in your dorm room using a random numbers table because the server is down and you cannot use an on - line random numbers generator. Your roommate, who is patiently waiting for you to finish so you can go out, offers to write down a list of 60 random numbers between 001 and 300 for you so you can be done quickly. In about three to four sentences, explain to your roommate why she is not likely to create a list of random numbers.
