1. One behavioral strategy to reduce food intake is to eat slower in order to allow physiological fullness signs to be detected (Azrin et al., 2008). To test this a researcher provides one group with instructions to eat fast and a second group instructions to eat slow. The number of calories consumed is recorded. Test whether rating of eating influenced number of calories consumed using a .05 level of significance. What is the effect size for this study? What is the 95% confidence interval for this study?

**Slow Group:**
- Mean (\( \bar{x} \)) = 290
- Sum of Squares (SS) = 149,212
- Sample size (n) = 10
**Fast Group:**
- Mean (\( \bar{x} \)) = 470
- Standard deviation (s) = 152
- Sample size (n) = 8
