Chapter 15, Problem 19P

In a study similar to one conducted by Fallon and Rozin (1985). a psychologist prepared a set of silhouettes showing different female body shapes ranging from somewhat thin to somewhat heavy and asked a group of women to indicate which body figure they thought men would consider the most attractive. Then a group of men were shown the same set of profiles and asked which image they considered the most attractive. The following hypothetical data show the number of individuals who selected each of the four body image profiles.

a. Do the data indicate a significant difference between the actual preferences for the men and the preferences predicted by the women? Test at the .05 level of significance.

b. Compute the phi-coefficient to measure the strength of the relationship.

	Body Image Profiles
	Somewhat Thin	Slightly Thin	Slightly Heavy	Somewhat Heavy
Women	29	25	IK	8	80
Men	11	15	22	12	60
	40	40	40	20
