A librarian would like to determine whether a new book appeals more to adults or to children. The librarian asks 10randomly selected adults and their children whether or not they will be interested in reading the book. The librarian then sorts the responses into two samples: one sample for the adults' answers and one sample for their children's answers. Are these samples independent? If not, how can these samples be made independent? Select the correct answer below: A) Yes, the samples are independent. B) No, the samples are dependent. To make the samples independent, the librarian should take a random sample of adults and then separately take a random sample of children who are not related to those adults. C) No, the samples are dependent. To make the samples independent, a larger sample of adults with their children should be taken. D) No, the samples are dependent. To make the samples independent, the librarian should make sure to ask about the book over multiple days.
