Approximate Confidence Intervals for a Population Proportion As a consequence of the last theorem, one may write : So , solving for p inside the parentheses of P ( ) , one obtains Let’s see how to use this statement to obtain an approximate two-sided confidence interval ...
A population proportion is the share of a population that belongs to a particular category.Confidence intervals are used to estimate population proportions. Estimating Population ProportionsA statistic from a sample is used to estimate a parameter of the population....

In this paper, we consider the problem of estimating the population proportion in pair ranked set sampling design. An unbiased estimator for the population proportion is proposed, and its theoretical properties are studied. It is shown that the estimator is more (less) efficient than its ...

The bias and mean squared ...
Children under five made up 12% of the population with household exposure, while adults were 65%. Zimbabwe, Mozambique, Zambia, and Pakistan had the highest proportion of the population with household exposure, while India had the highest number of contacts (11·4 million, 95% UI 9·7-13·...

(Manly & Parr1968). While this method does require sampling a relatively high proportion of the total population (> 25% for populations with less than 250 individuals and > 10% for larger populations) and can produce larger standard errors than other open population models, it is ...
The proportion of heavy duty vehicles is 11% and the speed limit is set to 50 km h−1. The traffic loads are especially high during rush hours at 8 a.m. and 5 p.m.. Both sides of the street have rows of buildings which weaken the dispersion process of the direct vehicular ...
