FAN AND MEDAL
Jack wants to know how many families in his small neighborhood of 60 homes would help organize a neighborhood fundraising 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 help organize the fundraising party. He found that 12% of the families would help organize the party. He claims that 12% of the neighborhood families would be expected to help organize the party. Is this a valid inference?
