Finite and infinite population sampling
WebBut if the population size is N it will be. [ p ( 1 − p) / n] [ 1 − n / N]. The finite population correction factor, ( 1 − n / N), will make it go to 0 as n approaches N rather than be p ( 1 − p) / N that you would get for a single proportion assumong an infinite population. For your two sample problem the formula is a little more ... Web225 1 5. (1) In your example sampling n = 1000 from among N = 10, 000, there is not much difference between sampling with and without replacement. You are sampling only 10% of the population and interviewing a given individual twice will be relatively rare. (2) However, in sampling without replacement, the X i are not independent.

WebSampling from a Finite Population: Interval Estimation of Means, Proportions and Population Totals Jerry Brunner March 21, 2007 Most of the material in this course is based on the assumption that we are sampling with replacement, or else sampling without replacement from an “infinite population” (definitely a theoretical abstraction. WebMar 7, 2011 · In the infinite population case, the sample mean has a normal distribution with mean 76 and standard deviation , where is the sample size. Sampling in the finite population is without replacement. In this case, the variance of the sampling distribution for the mean is adjusted by multiplying by the finite population correction factor , where is ...
