Best ResponseYou've already chosen the best response.0Sue wants to know how many families in her small neighborhood of 50 homes would volunteer to help at a neighborhood animal shelter. She put all the addresses in a bag and drew a random sample of 25 addresses. She then asked those families if they would volunteer to help at the shelter. She found that 18% of the families would volunteer to help at the shelter. She claims that 18% of the neighborhood families would be expected to help at the animal shelter. Is this a valid inference? Yes, this is a valid inference because the 25 families speak for the whole neighborhood Yes, this is a valid inference because she took a random sample of the neighborhood No, this is not a valid inference because she only asked 25 families No, this is not a valid inference because she did not take a random sample of the neighborhood
