Q. Bella wants to conduct a survey to determine how many of the residents of Forks believe in supernatural creatures.Which of the following survey methods will allow Bella to make a valid conclusion about the percentage of residents of Forks that believe in supernatural creatures?Choose answer:(A) Ask a randomly selected sample of residents to answer the question anonymously.(B) Ask a randomly selected sample of high school students to answer the question anonymously.
- Population Representation Method: Bella needs a method that represents the whole population of Forks, not just a specific group like high school students.
- Option A: Random Sample of Residents: Option A suggests asking a randomly selected sample of residents, which would include people from different age groups and backgrounds.
- Option B: Random Sample of High School Students: Option B suggests asking a randomly selected sample of high school students, which is not representative of the entire population since it only includes a specific age group.
- Choosing a Representative Option: Since we want a valid conclusion about all residents, we should choose the option that represents the whole population.
