Suppose you want to take a scientific poll about people's opinions on a new boating law for Lake Blue. Who should make up your universe, all people in the US, only townspeople, only boat owners, only people who live on the lake, anyone who uses Lake Blue, or some other group?

I suggest that the best poll would be just the people who live on the lake.

When conducting a scientific poll about people's opinions on a new boating law for Lake Blue, it's important to determine the appropriate population, also known as the "universe," to survey. The choice of universe depends on several factors, including the specific objectives of the poll and the scope of the law in question. Here are a few possible options for defining the universe:

1. All people in the US: This option includes opinions from a wide range of individuals, regardless of their location or connection to Lake Blue. It provides a national perspective on the issue and captures views from various demographics. However, it may also include people who are unfamiliar with Lake Blue or the specific boating law.

2. Only townspeople: By focusing on the residents of the surrounding towns near Lake Blue, you can gather opinions from individuals who are likely to be directly affected by the new law. This option allows for a more localized understanding of the issue and may be particularly relevant if the law primarily impacts the townspeople.

3. Only boat owners: If the boating law specifically targets individuals who own boats, surveying only boat owners can provide valuable insights from the group directly affected. It allows for a specific perspective on how the law may impact this particular segment of the population.

4. Only people who live on the lake: If the law primarily affects those residing on Lake Blue, surveying this specific group can offer insights into the opinions of individuals who have a direct connection to the lake and its activities.

5. Anyone who uses Lake Blue: This option encompasses a broader population than just those living on the lake. It could include individuals who visit the lake, participate in recreational activities there, or have a general interest in its affairs. This approach captures a wider array of opinions from people who are directly or indirectly connected to the lake.

Ultimately, the choice of the universe will depend on the specific goals of the poll and the intended scope of the boating law. Consider factors such as geographical boundaries, the targeted demographic, and the relevance of opinions based on direct or indirect involvement with Lake Blue.
