Agroup 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 feeding practices of horses admitted to the veterinary hospital. to obtain a random sample of the 5000 horses that had been admitted over the last 10 years to the hospital, they sequentially assigned numbers starting with 1 to the horses in order of admittance. they then picked a random starting point and decided to sample every 100th horse to get a random sample of 50 horses. this procedure corresponds to a:
a. simple random sample because all horses have the same chance of being picked.
b. systematic sample because not all sample are possible. c. stratified random sample because the procedure is obviously not a simple random sample.
d. none of the answer choices is correct.
