B. ​Yes, there is reason. The TV audience might not be representative of the population.

C. ​No, there is not reason. There is no bias in the study.

D. ​Yes, there is reason. The wording of the question might produce inaccurate or dishonest responses.

E. ​Yes, there is reason.​ Call-in polls tend to be biased.

F. ​No, there is not reason. It is unlikely that there are any confounding variables in the study.

Answer 1

B. ​Yes, there is reason. The TV audience might not be representative of the population.

Explanation:

The question "Do you support new national mileage standards for​automobiles?" is asked to the TV audience.

Therefore those who will voted are the ones who are watching the TV show. We do not know the rate of people who do not watch TV or who do not watch that TV talk show in the population.

Thus the results cannot represent the whole population
