1.     How do the following terms 'Relevant', 'Reliable' and 'Sufficient' relate to audit evidence? What are

2. Internal auditing is going to be performing an assurance engagement dealing with controls over ordering, invoicing and collections. Some of the items to be covered in the engagement include:  

·        Determine if prices on the invoices are correct 

·        Determine if all material shipped has been invoiced

·        Determine why the number and amount of credit memos issued to customers have increased by 20% over the previous year while sales have only gone up by 5%.  

·        Determine if volume rebates are authorized and correctly calculated 

·        Determine if sales are being made to customers in violation of laws and regulations (e.g. export restrictions).  

With one of these items, what two tests are the most appropriate to gather the required evidence. Why those test are most appropriate.
