The population is a collection of objects that we want to study/test. For example, if you are studying quality of products from an assembly line for a given day, then the whole production for that day is the population. Webfrom a finite population where the variable has no specified distribution. Little’s Approach Little (2004) formulated the sample-to-population inference for one mean as a Bayesian type of stratified random sampling problem rather than a simple random sampling problem.
