9.64 Female Models In a study to assess various effects of using a female model in automobile adver- tising, 100 men were shown photographs of two auto- mobiles matched for price, colour, and size, but of different makes. One of the automobiles was shown with a female model to 50 of the men (group A), and both automobiles were shown without the model to the other 50 men (group B). In group A, the auto- mobile shown with the model was judged as more expensive by 37 men; in group B, the same automo- bile was judged as the more expensive by 23 men. Do these results indicate that using a female model influences the perceived cost of an automobile? Use a one-tailed test with a = 0.05.
