A population consists of 500 members and a simple random sample of 100 members is to be selected. Which of the following represents the most efficient method for labeling the members for selecting the sample using a random number table?
a. 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, , 99, 100.
b. 1 = labels 001 and 501, 2 = labels 002 and 502, 500 = labels 500 and 000.
c. 001, 002, 003, , 499, 500.
d. 1 = labels 001, 101, 201, 301, , 901; 2 = labels 002, 102, 202, 302, , 902; and so on.
Question 2
A class consists of 30 students and the instructor wants to take a simple random sample of 5 students from this class. The students are labeled 01 to 30 for the selection process. Which of the following possible samples of size n = 5 is most likely to be selected?
a. 11, 18, 10, 08, 25.
b. 05, 10, 15, 20, 25.
c. 01, 02, 03, 04, 05.
d. None of the above, as they are all equally likely samples.
