For an appropriately randomized experiment, it’s ideal to select a population that allows for a diverse sample that can be generalized beyond a specific subgroup.
Considering the options:
- **Population #1: dogs in California** - This population is diverse and includes various breeds, sizes, and ages, allowing for a more randomized and generalizable study.
- **Population #2: golden retrievers in Omaha, Nebraska** - This population is very specific (only one breed and a specific location), which may limit the generalizability of the results.
- **Population #3: poodles in the United States** - Similar to Population #2, this is limited to only one breed.
Given this analysis, the best option for an appropriately randomized experiment would be:
**Population #1: dogs in California**
