文档标签: the The mean Mean THE Confidence Intervals: Estimating the Population Mean, µ In a sampling distribution that is Normal, what percent of the sample means fall within 2 standard deviations of the mean? This means that ___ percent of the time, when a sample mean is selected from...
a class of ratio estimators of a finite population mean using two auxiliary variables 热度: estimating mean cost using auxiliary covariates 热度: Performance evaluation of re-entrant manufacturing system with production loss using mean value analysis ...
One problem considered is the use of this data to estimate certain of the population percentage points for which the corresponding sample data was deleted. Another problem is to estimate the population mean and standard deviation. This paper presents solutions to these problems which are valid for ...
Small enough relative to the population size that the correction factor is close to 1. Confidence Interval (CI) μ: ¯X±Z⋅SEμ: X¯±Z⋅SE p:^p±Z⋅SEp:p^±Z⋅SE where ¯X,μX¯,μ are sample mean and population mean respectively, ^p,pp^,p are sample percents an...
Thus, we reconsider one of the basic questions in the observational study of ocean turbulence: When a vertical profile of the energy dissipation rate is given, how can one estimate the energy input rate or the population mean of the energy dissipation rate for a profile, which has been common...

Mean Squared Error (MSE)Relative EfficiencySimple Random Sampling without Replacement (SRSWOR)Probability Proportional to Size (PPS) SamplingThe paper deals with a generalized estimator of population mean which includes several estimators as its particular cases. Under certain conditions, the proposeDubey,...
Instead you want to make inferences about the parameters of the population the sample of data is drawn from. An inference may be an estimate of a parameter, or a hypothesis test if a parameter is equal to a specific value.On the Analyse-it ribbon tab, ...
In this paper a class of improved estimators has been proposed for estimating population mean in two phase (double) sampling when only partial information is available on either of two auxiliary variables. Under simple random sampling (SRWOR), expressions of mean square error and bias have been ...
On estimating the population mean using auxiliary character in stratified random samplingThis paper suggests new ratio estimators in stratified random sampling using the information of an auxiliary attribute. Theoretically, it is obtained the bias and mean square error (MSE) for these estimators and ...
