Please i need help in answering these auditing questions. thank you.

Chapter 9- Audit Sampling

• How to evaluate the results of a sample
• What is a tolerable rate/ tolerable misstatement
• How to calculate the audited value using (meanper-unit, difference estimation, and ratio methods)
• Attribute samples what are they used for, what are the key inputs to determine sample size
• Different methods used to pick samples from a population
• The difference between statistical and nonstatistical samples
• What is the risk of assessing control risk to high/low and the risk of incorrect acceptance/incorrect rejection
• What are some of the auditors concerns when picking a sample what can go wrong
• Relationship of tolerable rate/materiality, risk of assessing control risk too high/too low, population, expected deviations, etc. to sample size.

• Understand PPS sampling what are the steps to performing this sampling technique, understanding what a sampling interval is, and how it is calculated
• Why and when is PPS sampling the best method to use, what are some flaws and positives of PPS sampling
• Understand the definition of standard deviation
• Difference between CVS (classical variable sampling) and PPS
• Understand how to evaluate the results of a PPS sample (Tainting percentage, when projection makes sense, etc)
• Understanding when ratio estimation technique to evaluate a CVS sample is the best way to calculate differences/estimate population value.
• Understand what causes sample sizes to increase and decrease in CVS and PPS sampling
• Understand key terms such as tolerable misstatement, expected misstatement, recorded amount, audited amount.
