Answer:

Using a sample is more accurate, because more care must be taken assessing each response.

Explanation:

A "sample" is considered more accurate than a population because it prevents bias when it comes to responses--provided that each response was carefully assessed. This can give an exact representation of the entire population.

It is definitely not more expensive, not more time-intensive nor wasteful because it is more manageable, cost-effective and feasible than a population.
