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, Bauser, 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. Males Females n=6 n=9 M = 31 M = 45 SS = 490 SS = 680 (a) Based on these results, is there a significant difference between the attitudes for males and for females? Use a two-tailed test with = .05. (Use 3 decimal places.) t-critical = 2.048 t= Conclusion Fail to reject the null hypothesis, there is a significant difference in attitudes between males and females. Reject the null hypothesis, there is a significant difference in attitudes between males and females. Fail to reject the null hypothesis, there is not a significant difference in attitudes between males and females. Reject the null hypothesis, there is not a significant difference in attitudes between males and females. (b) Compute r2, the percentage of variance accounted for by the gender difference, to measure effect size for this study. (Use 3 decimal places.)
