Combine the data in Exercise 19.14 by adding together the Maintainers and Gainers categories.

Then compute an odds ratio to say something about racial differences in high-school girls’

perceptions of weight.

Exercise 19.14

In a study of eating disorders in female adolescents, Gross (1985) asked each of her participants whether they would prefer to gain weight, lose weight, or maintain their current weight.

(Note: Only 12% of the girls in Gross’s sample were actually more than 15% above what normative tables say they should weigh, a common cutoff for a label of “overweight.”) When she broke down the data for girls by race (African-American versus White), she obtained the following results. (Other races have been omitted because of small sample sizes.)
