Mathematical Proceedings of the Royal Irish Academy, Vol. 99A, No. 2 (Dec., 1999), pp. 171-177 (7 pages) In this paper we derive the exact covariance of some sample moments for 'simple random sampling ...

Modified efficiency comparisons, which take into consideration the fact that the expected number of distinct units in a with-replacement sample need not be an integer, are made for the same expected ...

Consider a population of 70 individuals, for which you wish to estimate the mean annual income, μ. Assume that you have decided to use the following estimation procedure to make your estimate: simple ...

(1) Simple random sampling is usually done without replacement (so there is no chance of the same individual appearing twice in the sample). In this case, there is a ...
