Question

the election of 2000 demonstrated that a poll isnt reliable if which of the following occurs?
the sample is too small.
too many states are red.
the sample is biased.
the election is too close to call.

Explanation:

A reliable poll requires a representative sample. A biased sample means certain groups are over - or under - represented, skewing results. Small sample size can also be an issue but a biased sample is a more fundamental problem. The color of states and closeness of an election do not directly affect poll reliability.

Answer:

The sample is biased.
