Chapter 8 Exercise 21 What is sampling error? It is the difference between the sample mean and the population mean Could the value of the sampling error be zero? Yes it is possible to have a zero sampling error. However‚ it is very low probability that this could happen. If it were zero‚ what would this mean? This means that the population is uniform and the sample mean and the population mean are equal. Exercise 22 List the reasons for sampling. Give an example of each reason
