Jack wants to know how many families in his small neighborhood of 60 homes would help organize a neighborhood fund-raising party
seraphim [82]

hello,


Jack wants to know how many families in his small neighborhood of 60 homes would help 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 help organize the fund-raising 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?


Yes, this is a valid inference because the 30 families speak for the whole neighborhood


it's the correct one because if he ask 30 families so they talk to their neighborhood so its will be 60 ;) so its correct,


hope this help
