STAT 200 Homework Week 08 Lane Chapter 15 #10 If an experiment is conducted with 5 conditions and 6 subjects in each condition, what are dfn and dfe? degree of freedom =>n =5 Total degree of f... reedom =29 degree of freedom of error => 29-5=24 #17 The following data are from a hypothetical study on the effects of age and time on scores on a test of reading comprehension. Compute the analysis of variance summary table. #28 ADHD Treatment (AT) case study (AT) The dataset ADHD Treatment has four scores per subject. a. Is the design between-subjects or within-subjects? the design is within subjects b.

Do athletes and non-athletes differ significantly in how much anger they express? Do the genders differ significantly in Anger Expression Index? Is the effect of sports participation significantly different for the two genders? Since p-value for gender is 0.55 which is large enough to accept null hypothesis of no effect. We can conclude that genders do not differ significantly in Anger Expression Index. The p-value for sports is 0.005 which is very we reject the null hypothesis of no effect. We can conclude that sports differ significantly in Anger Expression Index. The p-value for interaction is 0.678 which is large enough to [Show More]
