Five persons, who were suffering from depression, attended 10 one-hour counseling sessions. The following table gives the depression scores (on a scale of 1 to 10) of these five persons before and after attending the counseling sessions. Note that a higher score means that a person has a worse case of depression. Before 7.5 6.4 8.6 9.1 7.8 After 4.3 5.1 6.2 6.9 7.2 Let the paired difference d be defined as the score before minus the score after attending the counseling sessions. Use the above information to answer the following question: 26. The mean of the sample paired differences is: b. .76 a. 2.18 c. 1.94 d. 3.56
