Suppose East Arketia's government now reports that its

population mean disposable household income is $925 per month, with a standard deviation of $70.

The

population mean for yearly color was 4.8 and ranged between 3.6 and 6.4 (Table 1).

A Type I error is committed upon rejection of a true null hypothesis in favor of a false alternative, where the null hypothesis is the postulation that the

population means are equal and the alternative is the conjecture that one mean is larger than the other.

that is, at equilibrium, the

population mean will coincide with the mode of the fitness function.

In the field of survey sampling, the use of auxiliary information plays an important role in the estimation of

population mean of the variable under study both the design as well as the estimation stage and have greatly increase the efficiency of the estimators.

The 49

population means for all nine variables were subjected to principal components analysis.

They envisaged an estimator for the estimation of

population mean in the presence of non- response.

An alternative to selecting among phenotypes would be to select and discard whole populations based on the

population mean. The

population mean would be estimated with greater precision than the phenotypic value of individual lines.

In this research article, a class of ratio-type estimators has been proposed for the estimation of finite

population mean under simple random sampling scheme when there is maximum and minimum values.

Figures from demographic consultants, Macroplan Australia, show that record overseas migration and an ageing

population mean migrant families will overtake the number of locally born residents within 15 years, far sooner than previously imagined.

She said the recession and the soaring elderly

population mean more people want to work longer.

More recently, several authors have proposed efficient estimators of finite

population mean using two variables or attributes, including, Abu-Dayyeh et al.
