Answer:
A. Every tenth person working for the largest corporation in town
Step-by-step explanation:
We are given that,
'Valeriya wants to determine the likely voting outcome for the new town council election'.
It is required to find the most biased outcome.
Now, from the options, we see that,
'Every tenth person working for the largest corporation in town'.
will yield the most biased result, as the people working in the largest corporation may have different opinions and benefits.
So, it is most likely that the voting result for this sample may result in the outcome beneficial to only the people working in the large corporations and not for others.
Thus, sample A will yield a most biased result.
