Question: A tire manufacturer maintains strict quality control of its tire production. This entails frequent sampling of tires from large stocks shipped to retailers. Samples of tires are selected and run continuously until they are worn out, and the average number of miles "driven" in the laboratory is noted. Suppose a warehouse contains 11,000 tires arranged in a certain order. The company wants to select a systematic sample of 50 tires to be tested in the laboratory. Use randomization to determine the first item to be sampled, and give the rule for obtaining the rest of the sample in this case.
