Finite Population Sample Size Formula. Where n is the sample size and N is the population size. Finite and Infinite Population A scenario where the sample size n is MORE THAN 5 OF THE POPULATION SIZE N is called a FINITE POPULATION.
Derive Sample Size Equation Used For Proportions Youtube from www.youtube.com
Formulas for Sample Size SS For Infinite Sample Size. Is the sample size necessary for estimating the proportion p for a large population. N NX X N 1 where X Z α22 p 1-p MOE 2 and Z α2 is the critical value of the Normal distribution at α2 eg.
Therefore the sample size can be calculated using the formula as 10000 196 2 05 1-05 005 2 10000 1 196 2 05 1-05 005 2 Therefore 370 customers will be adequate for deriving meaningful inference.
