In a study to assess various effects of using a female model in automobile advertising
Chapter 10, Problem 10.58(choose chapter or problem)
In a study to assess various effects of using a female model in automobile advertising, each of 100 male subjects was shown photographs of two automobiles matched for price, color, and size but of different makes. Fifty of the subjects (group A) were shown automobile 1 with a female model and automobile 2 with no model. Both automobiles were shown without the model to the other 50 subjects (group B). In group A, automobile 1 (shown with the model) was judged to be more expensive by 37 subjects. In group B, automobile 1 was judged to be more expensive by 23 subjects. Do these results indicate that using a female model increases the perceived cost of an automobile? Find the associated p-value and indicate your conclusion for an = .05 level test.
