Did you sleep with a comfort object as a child? Do you still? No need to stuff that teddy bear from your infant years in your closet the next time you have a guest over—the odds are good that he or she has a comfort object, too. A study conducted by Sleepopolis and OnePoll reported that 34% of adults still sleep with a stuffed animal, blanket, or other sentimental object, according to a survey of a random sample of 100 adults. A similar study, based on a random sample of 80 children reports that 75% of children sleep with a comfort object. Do these data provide convincing evidence that the proportion of adults who sleep with a comfort object is less than the proportion of children who sleep with a comfort object? Justify your answer.
