What are the implications of selecting either a larger or smaller sample size than those determined using the tables? Calculate the SER and CUER for each population. For which of the six populations should the sample results be considered unacceptable? What options are available to the auditor? Why is analysis of the exceptions necessary even when the populations are considered acceptable? For…

Basic Sampling: Comprehensive. Reagan Russell is considering opening a multipurposehardware and lawn store in Anytown, USA. Based on his knowledge of the industry, hebelieves that if the average household income is more than $35,000, the store will ultimatelybe successful. He was planning to attempt a census of the income levels in Anytown but hasheard about sampling and is now considering using sampling to obtain the necessary information to make his decision. Required:a. What would you tell Russell about the advantages and disadvantages of sampling?b. Russell is interested in knowing the advantages and disadvantages of statistical sampling.What would you tell him?c. Russell has heard about sampling and nonsampling risk and is concerned about them.1. Define sampling risk and nonsampling risk.2. How can Russell control his exposure to sampling and nonsampling risk?3. What are some possible examples of sampling and nonsampling risk in this situation?d. Assume that Russell decided to use…
