The local news is conducting a poll of the residents’ opinions regarding a new traffic law that is being proposed. At the end of a news segment, viewers had the opportunity to dial in or use social media to choose whether they agree or disagree with the law. A large sample size was represented, and this poll was repeated again one week later with similar results. When working with this data, which of the following statements best applies? a. The surveys are biased because people chose to respond or not.
b. Because of the large sample size, the results are most accurate of all members of the community.
c. The same sampling methods were used for both polls, demonstrating reliability.

Option A is correct.

The surveys are biased because people chose to respond or not.

Step-by-step explanation:

When humans are given the choice whether to participate in a poll like in this question, most often than not, the poll is biased.

This is because only the people or set of people who feel strongly the most about the subject matter of the poll will participate in the poll. This favours the group that disagrees as this group, if given the choice to express their opinion, will most likely be the set of people that will readily express their discontent.

Discontent is more visibly and strongly expressed in humans.

In order to remove this bias, people should have been chosen at random and their responses recorded.

The two other options are not absolutely correct, these are the reasons.

b. Because of the large sample size, the results are most accurate of all members of the community.

Like I expressed above, the base of the sample is flawed and biased as it will most likely favour a group of the population that don't agree with the law. So, no matter how large the sample is, that type of bias makes the poll unreliable.

c. The same sampling methods were used for both polls, demonstrating reliability.

The sampling method is biased, so, it doesn't matter if it is repeated for both polls. it most likely will not represent the correct general consensus about the new traffic law.

Hope this Helps!!!
