He then asks those families if they plan to attend the party. He finds that 20% of the families plan to attend the party. He claims that 20% of the neighborhood families would be expected to attend the party. Is this a valid inference? plzzzzzzzzzzzzzzzzzzzzzz help

    No, this is not a valid inference because he asked only 20 families No, this is not a valid inference because he did not take a random sample of the neighborhood Yes, this is a valid inference because he took a random sample of the neighborhood Yes, this is a valid inference because the 20 families speak for the whole neighborhood

    Carla wants to know how many students in her school enjoy watching reality TV shows. She asks all 22 students in her science class and finds that 40% of her classmates enjoy watching reality TV shows. She claims that 40% of the school's student population would be expected to enjoy watching reality TV shows. Is Carla making a valid inference about her population?

    about her population? No, it is not a valid inference because her classmates do not make up a random sample of the students in the school No, it is not a valid inference because she asked all 22 students in her science class instead of taking a sample of the students in her school Yes, it is a valid inference because she asked all 22 students in her science class Yes, it is a valid inference because her classmates make up a random sample of the students in the school
