Extracted text: Let N=6 and n=3. For purpose of studying sampling distribution, we assume that all population values are known. In this study, two sampling plans are proposed. In Sampling Plan 1, eight possible samples are chosen. Meanwhile, in Sampling Plan 2, only three possible samples are chosen. Number of Element Population in Population 99 1 2 104 3 156 130 4 189 173 6 Sampling Plan 1: {1, 3, 5} {1, 3, 6} {1,4, 5} {1,4, 6} {2, 3, 5} {2, 3, 6} {2, 4, 5} {2, 4, 6} Sampling Plan 2: {1, 4, 6} {2, 3, 5} {1, 3, 5} (i) Compute the value of population mean. (ii) For each sampling plan, compute the value of estimated mean and bias. (iii) Which sampling plan do you think is better?
