Several students were tested for reaction times (in thousandths of a second) using their right and left hands. (Each value is the elapsed time between the release of a strip of paper and the instant that it is caught by the subject.) Results from five of the students are included in the graph to the right. Use a 0.05 significance level to test the claim that there is no difference between the reaction times of the right and left hands. 220- 170- Reaction Time Data Table 120- 120 160 200 Right Hand Right Hand Left Hand Wh 128 128 Let 122 149 Ind left hand reaction times. 147 161 Ho 199 180 160 206 Print Done Left Hand
