Consider a finite population U of size N = 5. We consider the following sample design:
s | {1, 2} | {3,4} | {3, 5} | {4, 5} | {2, 4} |
p(s) | 1/4 | 1/6 | 1/6 | 1/6 | 1/4 |
Table 1: The sample design
(i) Determine the first-order inclusion probabilities.
(ii) Determine the second-order inclusion probabilities.
(iii) Does this sample design correspond to simple random sampling without replacement? Systematic sampling? Bernoulli sampling? Justify your answers.
