Mark wants to know how many families in his neighborhood plan to attend the neighborhood party. He puts all 80 of the neighborhood addresses in a hat and draws a random sample of 20 addresses. 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?

Best ResponseYou've already chosen the best response.0about 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
