08.01)sam wants to know how many families in his neighborhood plan to attend the neighborhood cookout. he puts all 100 of the neighborhood addresses in a hat and draws a random sample of 25 addresses. he then asks those families if they plan to attend the cookout. he finds that 15% of the families plan to attend the cookout. he claims that 15% of the neighborhood families would be expected to attend the cookout. is this a valid inference?
yes, this is a valid inference because he took a random sample of the neighborhood
yes, this is a valid inference because the 25 families speak for the whole neighborhood
no, this is not a valid inference because he asked only 25 families
no, this is not a valid inference because he did not take a random sample of the neighborhood
i think yes because he took a random sample, and the found the percent and multiplied it by the total number of families
