  1. Answer:
    Yes, this is a valid inference because she took a random sample of the neighborhood.
    Step-by-step explanation:
    As we can see, Sue’s survey was perfectly random and without any prejudice.
    18% of the families, according to her research, would volunteer at the shelter. According to her, 18% of the local households should be required to volunteer at the animal shelter.
