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 random sample of the 5000 horses that had been admitted to the hospital over the last 10 years, the veterinarians sequentially assigned numbers (starting with 0001) to the horses, in order of admittance. They then picked a random starting point and decided to sample every hundredth horse to get a random sample of 50 horses. This procedure corresponds to:

Systematic Sampling

Step-by-step explanation:

The procedure corresponds to systematic sampling because Systematic sampling is a method of probability sampling whereby sample members from a larger population are selected in order of a random starting point but in a fixed, periodic interval.

Now, in the question we are told that they picked a random starting point and decided to sample every hundredth horse to get a random sample of 50 horses. Since random starting point in corresponds to Systematic Sampling.

Another reason why it's a systematic sampling is because they sampled every hundredth horse and therefore not all the samples were considered.

uhhh idk u yolo?

to determine the unit cost your would divide the total cost by the number sold.
