Question

Quizplus · Accepted Answer

To create unique code numbers for each member of the population, we need enough digits to avoid repeating any codes. With a population of 72,345, a 5-digit code number is necessary to ensure uniqueness. A 4-digit code number would only allow for 10,000 unique codes, while a 6-digit code number would provide more than enough unique codes, but would be unnecessary and potentially time-consuming to generate and manage. A 3-digit code number would not be sufficient to ensure uniqueness with a population of this size.
