Answer: Sarah failed to evaluate a potential ethical issue.
Explanation:
From the question, we are informed that Sarah who is the controller of a large beverage supplier, supervises two employees and that her boss, Vladimir, told her to increase the company's inventory balance for an amount that is material to the financial statements by crediting several small "miscellaneous" expense accounts. 
We are further told that Sarah does not know the reason behind this but told one of her staff to make them because she has been instructed to do so. 
We can see that Sarah failed to evaluate a potential ethical issue. She didn't evaluate the effect of what she is doing. In this case, what her boss told her to do could be a case of fraud and she just obliged without asking questions which will put her conscience at ease in case anything happens but the fact that she just did it without asking questions or thinking if what she has done is morally right or wrong, it shows that Sarah failed to evaluate a potential ethical issue. 
 
        
             
        
        
        
The size of the sample that must be used is 264. The correct sample size is 264. Read below about how to arrive at the sample size.
<h3>What is the sample size that must be used?</h3>
p′ = x / n where x represents the number of successes and n represents the sample size. The variable p′ is the sample proportion and serves as the point estimate for the true population proportion.
Then, it follows that,
p= 30/10 x 88 = 264
Therefore, the correct answer is 264.
