The president of the student council wants to survey the student population about parking. She decides to take a random sample of 100 of the 1,020 students at the school. She gets an alphabetical list of the students, and numbers them from 0001 to 1020. Then, using a random number table, and starting at a random line, she selects 100 unique numbers between 0001 and 1020. Is this a simple random sample? No, because the sample could contain repeating numbers. No, because the sample could contain numbers other than numbers between 0001 and 1020. Yes, because each student and sample of 100 has the same chance of being selected. Yes, because each student is represented by a 4-digit number from 0001 to 1020.
