A group of veterinarians at a major veterinary hospital was interested in investigating a possible link between enteroliths (stones that form in the colon of horses) and diet. They decided to conduct a survey of the feeding practices for horses admitted to the veterinary hospital. To obtain a simple random sample, they used a computer to generate 4-digit ID numbers for all horses. They used random digit tables to select the horses. Which of the following is a step in selecting a random sample by this procedure?
