Cell-in poll A local news program decides to conduct a poll to see how their viewers feel about their new programming format. At the end of each program during one week they ask viewers to call in and express their opinions. The station gives one number to dial if you like the new format, and another number to dial if you do not like it. Which of the following is a correct characterization of this sampling approach? A) This sampling approach will be biased because people might dial the number incorrectly, and therefore not everyone will be correctly represented.
B) This sampling approach will be biased because the people who call in will be those who have stronger feelings about the new format. and therefore the sample will not be representative of the population.
C) This sampling approach will be unbiased because people can call in with either opinion, therefore the sample will be representative of the population.
D) This sampling approach will be unbiased because the station doesn't know who will call in, making it a random sample.
