Select the best answer. Your statistics class has 30 students. You want to call an SRS of 5 students from your class to ask where they use a computer for the online quizzes. You label the students 01, 02, ..., 30. You enter the table of random digits at this line: 14459; 26056; 31424; 80371; 65103; 62253; 22490; 61181. Your SRS contains the students labeled.
(a) 14, 45, 92, 60, 56.
(b) 14, 31, 03, 10, 22.
(c) 14, 03, 10, 22, 22.
(d) 14, 03, 10, 22, 06.
(e) 14, 03, 10, 22, 11.

Respuesta :

(d) 14, 03, 10, 22, 06 is the right answer

Step-by-step explanation:

the random number table is used to select s sample randomly. In this method, all the members in the population are numbered from 01. As here the students are 30, two-digit numbers will be used.

In random number table, the row is being read from the left side, a pair of numbers at a time. If the pair of number falls inside the range of total population, the member on the number is selected.

Here,

14459; 26056; 31424; 80371; 65103; 62253; 22490; 61181.

As five students have to be chosen

So,

Pairing the numbers

14 45 92 60 56 31 42 48 03 71 65 10 36 22 53 22 49 06 11 81

14 falls in the range so it will be selected

03, 10, 22 and 06 will be selected. As 22 was selected already, it will not be considered again.

So selection is: 14, 03, 10,22,06

Hence,

(d) 14, 03, 10, 22, 06 is the right answer
