Performance obligation:
Revenue is recognized by a company if the contractual obligations are satisfied by transferring the goods and services to a customer. A performance obligation must be identified and separated.

The one-year warranty is given only on the purchase of the vacuum cleaner. This warranty cannot be sold separately.
Therefore. V should recognize this cost as a warranty expense in the period of sale.
The extended warranty for a period of three years is sold separately. This is a separate performance obligation since the warranty for quality assurance is extended beyond the original period of one year.
This warranty can be purchased by customers separately which is priced separately from the product. This extended period warranty is not included in the implied contract.
Therefore, there exists only one performance obligation in the contract.

Answer: a) Required minimum sample size= 219
b) Required minimum sample size= 271
Step-by-step explanation:
As per given , we have
Margin of error : E= 5% =0.05
Critical z-value for 90% confidence interval : 
a) Prior estimate of true proportion: p=28%=0.28
Formula to find the sample size :-
Required minimum sample size= 219
b) If no estimate of true proportion is given , then we assume p= 0.5
Formula to find the sample size :-
Required minimum sample size= 271
