Jack wants to know how many families in his small neighborhood of 60 homes would organize a neighborhood fund-raising party. he put all the addresses in a bag and drew a random sample of 30 addresses. he then asked those families if they would organize the fund-raising party. he found that 12% of the families would organize the party. he claims that 12% of the neighborhood families would be expected to organize the party. is this a valid inference? no, this is not a valid inference because he asked only 30 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 30 families speak for the whole neighborhood
