Question

29

For #20 - 29: A researcher would like to evaluate the effectiveness of a pain-relief patch designed for back pain. Prior to testing the patch, each of the patients (n = 7) rated their current level of back pain on a scale from 1 to 10. After wearing the patch for 90 minutes, a second pain rating is recorded. The data in this repeated-measures design are as follows: %3D Pain Pain D scores D2 SS variance ofD=s² df Before After 7 4 SMD n 9 4 n 5 t = Mp/ SMR. 3 %3D 4 1 | 29. What is your conclusion? Do you reject the null hypothesis or fail to reject the null hypothesis?
