Angela wants to know how many families in her neighborhood plan to attend the parade. She puts all 120 of the neighborhood addresses in a hat and draws a random sample of 30 addresses. She then asks those families if they plan to attend the parade. She finds that 40% of the families plan to attend the parade. She claims that 40% of the neighborhood families would be expected to attend the parade. Is this a valid inference? (5 points) A) Yes, this is a valid inference because the 30 families speak for the whole neighborhood

B) Yes, this is a valid inference because she took a random sample of the neighborhood

C) No, this is not a valid inference because she did not take a random sample of the neighborhood

D) No, this is not a valid inference because she asked only 30 families
