Document Summary
The difference method is a little off because the slope of the regression line is quite far from unity. : z : s for simple random samples of size 4, 8 for simple random samples of size 8, s. The pattern of past due accounts is cyclic since the past due accounts are the lower numbered accounts in each department. When the population of responses is cyclic, systematic sampling in general is worse than simple random sampling. 1-in-10 systematic samples which result in samples of size 4 may result in a sample selected from the higher account numbers in each department and therefore have no past due accounts in the sample. Note in part (a) that : ! s with probability 0. 3. A 1-in-10 sample may also result in all sampled accounts being past due as seen in part (a). As seen above, simple random samples of size.
