Question
Twelve people completed a difficult hand-eye coordination task twice: once in a quiet room, and once in the same room while loud rock-and-roll music was being played. The order in which subjects experienced these conditions was counterbalanced: half performed in the quiet environment first, half performed in the loud environment first. The researcher measured the number of errors committed by the participant while performing. Thus, the lower the score, the better the performance. Here are the results: Was there a significant difference in performance between the two treatment conditions (alpha - .05)? What is the test statistic and the p-value Participant 1 3 4 I5 6 17 8 10 11 12 Quiet Enviroment 14 21 24 16 18 20 15 20 17 16 19 12 Loud Enviroment 21 22 21 19 18 25 17 18 21 24 21 15 O t=2.6, P-value-0.9805 O t-1.5, p-value=0.067 O t-2.6, p-value=0.0233
