Question

Distinguish between Simple Random Sampling with Replacement (SRSWR) and Random Sampling without Replacement (SRSWOR).

Answer 1

Hey mate!!

In sampling without replacement, the two sample values aren't independent. ... In particular, if we have a SRS (simple random sample) without replacement, from a population with variance , then the covariance of two of the different sample values is , where N is the population size.

In sampling without replacement, the two sample values aren't independent. ... In particular, if we have a SRS (simple random sample) without replacement, from a population with variance , then the covariance of two of the different sample values is , where N is the population size.
