Final answer:
To set up the process for sampling, you need to determine the value of k by dividing the population size by the sample size. Then, you can randomly select the first element and continue selecting every kth element to form the sample. The locations of the first 4 elements would depend on the value of k.
Step-by-step explanation:
To set up the process for sampling, you need to determine the value of k by dividing the population size by the sample size: k = population size / sample size. In this case, k = 703,691 / 123. After finding the value of k, you can randomly select the first element and then continue selecting every kth element to form the sample.
a) If k = 5, the first element would be randomly selected, and then every 5th element after that. The first 4 elements would be the randomly selected first element, the element at position 6, the element at position 11, and the element at position 16.
b) If k = 6, the first element would be randomly selected, and then every 6th element after that. The first 4 elements would be the randomly selected first element, the element at position 7, the element at position 13, and the element at position 19.
c) If k = 7, the first element would be randomly selected, and then every 7th element after that. The first 4 elements would be the randomly selected first element, the element at position 8, the element at position 15, and the element at position 22.
d) If k = 8, the first element would be randomly selected, and then every 8th element after that. The first 4 elements would be the randomly selected first element, the element at position 9, the element at position 17, and the element at position 25.
