Question 160362 • NC-Math 4 CR

A school principal wants to conduct a survey of student electronic use in her high school. She wants to select an SRS of 50 from the 690 students in the school using a random number table.Which of the following are correct methods for labeling the population? Check all that apply.00–50000–689001–050001–690001–999

Answer
A
00–50
B
000–689
C
001–050
D
001–690
E
001–999

Explanation

Each student needs a unique label, and labels should use the same number of digits so they can be read consistently from a random number table. The ranges 000–689 and 001–690 each provide exactly 690 labels, one for every student. The other ranges do not: some contain too few labels, while 001–999 includes labels that do not correspond to any student.
