उत्तर
The procedure for selecting a random sample of 3 students out of 10 in a class is as follows:
- Assign a particular number between 1 to 10 to all the 10 students like 01, 02, 03, 04, 05, 06, 07, 08, 09, 10.
- Select a number randomly. Let us assume that the number selected is 05.
- Consult the Two-Digit Random Number Table, two numbers successive to the selected random number (i.e. 05) either horizontally or vertically are the remaining two students (i.e. 06 and 07).
