1. What does the increase of population mean to us?

2. Population mean of all the students in a teaching experiment of analytical chemistry should be regarded as the certified value.

3. What is the 95% confidence interval for the population mean?

4. What does a longer-living population mean for relationships and families?

5. Cytoplasmic effects also contributed to the population mean heterosis of some traits such as gel consistency and protein content.

5. try its best to collect and build good sentences.

6. This paper deals with the estimation of population mean in systematic sampling by use of auxiliary information in order to improve the accuracy of the estimate.

7. The population mean, denoted m, is a population parameter and is the average of the population measurements.

8. The strongly positive correlation between population mean and population variation decreased significantly compared the cysts per plant with transformed resistance value.

9. The paper proposes new separate ratio estimators for population mean using known skewness coefficient of auxiliary variable in stratified random sampling.

10. In a simple random sampling, the sample mean is an unbiased estimate of the population mean.

11. The method of central sampling was presented, which is sampling some units near population mean by general estimating and then taking the units mean as undeviating estimation of the population mean.

12. With the imputed values and the censored data, the confidence interval of the population mean is constructed in two different ways, one is asymptotic normal and the other is empirical likelihood.

13. We can define it in a couple of different ways depending on whether we're talking about sample mean or population mean.

14. We give the approximation formulas of the variance of the sample ratio estimator for a population mean and its asymptotically non-biased estimator in multi-stage sampling.

15. Limits around an experimentally determined mean within which the population mean lies with a given degree of probability.

16. Our estimator is asymptotically equivalent to a model-calibration (MC) estimator in Wu and Sitter (2001) in the case of estimating the finite population mean.

17. The calculation formulas of sample size based on the error limitation are given for estimation of population mean.
