Question: Do you view a chocolate bar as delicious or as fattening? Your attitude may depend on your gender. In a study of American college students, Rozin, Bauer, and Catanese (2003) examined the importance of food as a source of pleasure versus concerns about food associated with weight gain and health. The following results are similar to those obtained in the study. The scores are a measure of concern about the negative aspects of eating.

1. Based on these results, is there a significant difference between the attitudes for males and for females? Use a two-tailed test with α = .05.
2. Compute r2, the percentage of variance accounted for by the gender difference, to measure effect size for this study.
