The percentages do not add up to , so any possible conclusions from the poll are invalid.
Those who responded to the poll were not a random sample of the population of the United States.
There were not "Yes" responses and "No" responses.
The show did not allow viewers enough time to respond to the poll.
Explanation
Correct answer: B.
Choice B is correct. In order for the poll results from a sample of a population to represent the entire population, the sample must be representative of the population. A sample that is randomly selected from a population is more likely than a sample of the type described to represent the population. In this case, the people who responded were people with access to cable television and websites, which aren't accessible to the entire population. Moreover, the people who responded also chose to watch the show and respond to the poll. The people who made these choices aren't representative of the entire population of the United States because they were not a random sample of the population of the United States.
Desmos solution:
Note: The viewers chose both to watch this particular show and to respond to its website poll, so they form a self-selected sample rather than a random sample of the US population. The 28% and 70% results therefore cannot be generalized to the entire country.
