Answer

Brief Explanations:

Sampling bias occurs when the sample does not represent the entire population. In this case, only certain parts of the town are surveyed, so the sample may not be representative of all residents in terms of factors like income levels (which can affect opinions on electric - bill costs) that might vary by location in the town.

Answer:

D. Yes, it is biased. Only certain parts of the town were surveyed.
