(Use this information for questions 15-17). A researcher would like to determine if relaxation training will affect the concentration levels for hyperactive individuals. A week prior to training, each participant's concentration on a task is measured. Participants then receive relaxation training and following training their concentration is measured again. The data are as follows: Pre- Post- training training score (X₁) score (X₂) 36 37 39 40 42 41 34 36 36 37 32 31 29 30 30 30 31 32
