Question

Sex sells, part II In Exercise 11 you considered the ques-
tion of whether sexual images in ads affected people’s

abilities to remember the item being advertised. To inves-
tigate, a group of Statistics students cut ads out of maga-
zines. They were careful to find two ads for each of

10 similar items, one with a sexual image and one with-
out. They arranged the ads in random order and had

39 subjects look at them for one minute. Then they asked
the subjects to list as many of the products as they could
remember. Their data are shown in the table. Is there
evidence that the sexual images mattered?
