Sample computation of percentile
WebA sample is selected at random and without replacement in each of the strata. With respect to this sample, let- ni =the number of sampling units constituting the sample in the ith stratum, a=the number of A type sampling units in the sample ni, bi=the number of B type sampling units in the sample ni. WebMar 18, 2024 · The sample size is highly dependent on the width of the confidence interval as seen in the following table. Sample sizes are evaluated using the formula given in (3) with S U 2 = N p U ( 1 − p U) / ( N − 1), p U = 0.5 and z 0.975 = 1.96. The command to generate the sample sizes listed in the table below is.
