Find Minimum Sample Size. If the population is N then the corrected sample size should be 186N N185. 2 days ago Sample size is a research term used for defining the number of individuals included in a research study to represent a population.
To find this out you need to be clear about who. How to find the minimum sample size for a confidence interval for a mean using StatCrunch. Therefore the sample size can be calculated using the above formula as 10000 196 2 005 1-005 005 2 10000 1 196 2 005 1-005 005 2 Therefore a size of 72 customers will be adequate for deriving meaningful inference in this case.
HOW TO FIND a Critical Value using the z-table The n is the smallest sample size that will give us this error using this CI.
The formula to calculate a minimum sample size is as follows. Consider your sample size variables 1. Sample size This is the minimum sample size you need to estimate the true population proportion with the required margin of error and confidence level. The zc can be estimated with the number 2 because the actual z-table critical values for 95 CI is 196.
