Q. City Councilwoman Kelly wants to know whether the residents of her district support a proposed school redistricting plan. Which of the following survey methods will allow Councilwoman Kelly to make a valid conclusion about whether residents of her district support the proposed plan?Choose answer:(A) Ask her neighbors.(B) Ask the residents of Whispering Pines Retirement Community.(C) Ask residents of her district whose names are chosen at random.(D) Ask a group of parents at the local playground.
- Consider Options: Look at option (A) Ask her neighbors. This isn't a good choice because it's not a diverse or large enough group to represent the whole district.
- Evaluate Random Sample: Consider option B Ask the residents of Whispering Pines Retirement Community. This is also not representative of the entire district, as it only includes a specific group of people.
- Check Specific Group: Evaluate option (C) Ask residents of her district whose names are chosen at random. This method is likely to be the most valid because it uses a random sample, which should represent the entire district.
- Check Specific Group: Evaluate option (C) Ask residents of her district whose names are chosen at random. This method is likely to be the most valid because it uses a random sample, which should represent the entire district.Check option (D) Ask a group of parents at the local playground. This group is too specific and not random, so it wouldn't provide a valid conclusion for the entire district.
