please explain the answer .

Answer 1

There are 155 individual in the group

So the random sample of 8 individual from the group using the given random numbers

711 744 109  508 436 812 386 515 447 913 483 549  119 028  819 056 068 360 550 503 250 544 799 528 364 157 022 278 203 263 104 939 933 706 453 387 127 766 950 289

So the list of 8 individual from the group is- 109, 119, 028, 056, 068 , 022, 104, 127.

Expalantion- as the members of the group are numbered from 1 to 155. we will select the 3 digit numbers from the random number tables and the members corresponding to that numbers are selected.  

Here we cannot choose numbers like 278, 203 as these numbers does not correspond to any members.
