Answer
A
Given a population of size 400, use three-digit numbers to label each member.
B
Select the individuals or items that correspond to the randomly selected numbers.
C
If we have labeled our population with pairs of two-digit numbers, we would interpret a series of digits in the table reading 31645 as 31, 16, 64, 45.
D
While searching a series of digits, ignore zeros.
E
If we have labeled our population of two-digit numbers, we would interpret a series of digits in the table reading 03495 96193 as 03, 49, 59, 61, 93.
Explanation
For a population of 400, three-digit labels can identify members, and you select the members whose labels match the randomly chosen numbers. With two-digit labels, read digits in nonoverlapping pairs: 31645 gives 31, 64, and an incomplete final digit, not 31, 16, 64, 45. Zeros are not automatically ignored; in 03495 96193, the pairs are 03, 49, 59, 61, and 93.
