Final answer:
The range of random IDs that would cover all potential consumers is 1-1,000.
Step-by-step explanation:
The range of random IDs that would cover all potential consumers is option C) 1-1,000.
Since the researcher wants to select a random sample of consumers for a study from 0 to 1,000, the range of random IDs should cover all potential consumers. Option C) 1-1,000 includes all the numbers from 1 to 1,000, ensuring that no potential consumer is left out.
In this case, the random ID numbers should be generated from 1 to 1,000, rather than starting from 0, as there is no specified reason to include 0 as a potential ID number.
