They collected data from three different groups of patients: patients who were asked to continue therapy but not change their current exercise routine (no cardio condition), patients who were asked to continue therapy and increase their cardio exercise by walking five miles a week (mild cardio condition), and patients who were asked to continue therapy and increase their cardio exercise by running fifteen miles a week (intense cardio condition). After two months of treatment participants took a depression inventory, in which the lower their scores the fewer depression symptoms they were experiencing. The data from the study is displayed below. No Cardio Mild Cardio Intense Cardio n = 9 n = 9 n = 9 M = 17 M = 15 M = 11 T = 153 T = 135 T = 99 SS = 60 SS = 100 SS = 166 EX2 = 6041 G = 387 N = 27 What is the df total? 25 24 23 26 D Question 13 2 pts What is the df between? 4 2 1 3 D Question 14 2 pts What is the of within? 26 25 23\f10:09 1 LTE LTE +4 gcccd.instructure.com/course 15 G D Question 18 2.5 pts What is the MS between? 94 84 28 74 64 D Question 19 2.5 pts What is the 11.6 13.6 15.6 10.6 D Question 20 2.5 pts What is the computed F ratio? 8.19 7.19 6.19 10.19 D Question 21 2.5 pts What is the critical value for F from the F table? 4.40 5.40 2.40 3.40 D Question 22 2.5 pts Reject or fail to reject the null hypothesis?

Intense cardio and mild cardio significantly reduced depression scores compared to no cardio. No cardio significantly reduced depression scores compared to intense cardio. Among the three groups, there were no significant differences in depression scores between all three cardio conditions. Intense cardio significantly reduced depression scores compared to no cardio, whereas mild cardio was somewhere between no cardio and intense cardio in terms of depression outcomes, as it people who did mild cardio did not differ in their depression scores between either intense or no cardio groups. D Question 25 2.5 pts For questions 25 to 32 use the following prompt. For this you will perform an independent samples t test. A psychologist is interested in examining the effects of time spent outdoors on differences in the well-being of children. Using a well-being scale that ranges from 1 to 80, with higher values indicating a higher sense of well-being, she collects data from two separate groups of children and gathers the following information: Fewer than 12 hours a week More than 12 hours a week outdoors outdoors n = 10 n = 10 M = 70 M = 78 SS = 190 SS = 170 What is the degrees of freedom for this study? 20 18 19 21
