The following is a simplified dataset based on the Telch et al. (2001) study examining the effects of dialectical behavior therapy on binge eating disorder. In this simplified dataset, we'll say we performed a similar study and tested the effectiveness of dialectical behavior therapy on binge eating disorders. We'll say we randomly assigned 20 individuals diagnosed with binge eating disorder to one of two conditions with 10 different individuals in each group: (1) Dialectical Behavior Therapy (DBT) or (2) A waiting-list control group (WL). We then measured the number of days with a binge episode in a month (which could range from 0 to 31). Amount of binge days in a month are provided below and a lower score means fewer days with a binge episode. Perform the appropriate t-test, and use $?=.05$, two-tailed. Sums $(?)$ of each column are in bold at the bottom of the table. 10. What is the obtained value of $t$ ? 11. What is the critical value for $t$ ? This assessment may not be shared with others.

The number of binge days in the DBT group are not significantly different than those in the waiting-list control group. b. The number of binge days in the DBT group are significantly lower than those in the waiting-list control group. c. The number of binge days in the DBT group are significantly higher than those in the waiting-list control group. 13. What is Cohen's d (effect size for this problem)? (Round to two decimal places) 14. What is the lower limit of the $95\%$ confidence interval for this problem? (Round to two decimal places) 15. What is the upper limit of the $95\%$ confidence interval for this problem? (Round to two decimal places)
