Near the end of a US cable news show, the host invited viewers to respond to a poll on the show’s website that asked, "Do you support the new federal policy discussed during the show?" At the end of the show, the host reported that 28% responded "Yes," and 70% responded "No." Which of the following best explains why the results are unlikely to represent the sentiments of the population of the United States?
A)The percentages do not add up to 100%, so anypossible conclusions from the poll are invalid.
B)Those who responded to the poll were nota random sample of the population of theUnited States.
C)There were not 50% "Yes" responses and 50%"No" responses.
D)The show did not allow viewers enough time torespond to the poll

The results of the poll on the show’s website are unlikely to represent the sentiments of the population of the United States because the people who responded to the poll with a “Yes” or “No” were not a random sample: they were not selected in a way that was an unbiased representation of different groups/units that are part of the total population of the United States. In random sample/sampling, each group or subset has equal opportunity or probability of taking part in a poll; however, this was likely not the case in the poll because only the viewers took part in it.
