The result is the following formula for a confidence interval for a population proportion: p̂ +/- z* (p̂ (1 - p̂)/ n) 0.5 . Here the value of z* is determined by our level of confidence C. The formula given above for the standard error assumes that the population is infinite. Nonetheless, it is often used for finite populations when people are interested in measuring the process that created the existing finite population (this is called an analytic study). Though the above formula is not exactly correct when the population is finite, the difference between the finite- and infinite-pop… emergency protective order lawyer

WebbThe standard error is possibly the most important output from our analysis. It allows us to compute the margin of error and the confidence interval. When we estimate a mean or a proportion from a stratified random sample, the standard error (SE) of the estimate is: SE = (1 / N) * sqrt { Σ [ N 2h * ( 1 - n h /N h ) * s 2h / n h ] } WebbThe standard errorof p^{\displaystyle {\hat {p}}}is the square root of this quantity. Because we do not know p(1−p){\displaystyle p(1-p)}, we have to estimate it. Although there are many possible estimators, a conventional one is to use p^{\displaystyle {\hat {p}}}, the sample mean, and plug this into the formula.
