Twenty five right-handed students were asked to turn a knob (using their right hands) that moved an indicator by screw action. There were two identical instruments, one with a right-hand thread (the knob turns clockwise) and the other with a left-hand thread (the knob turns counterclockwise). The data presented below gives the times (in seconds) each subject took to move the indicator a fixed distance: Obs. # R 1 2 13 14 15 6 113 105 130 101 138 118 87 IL Obs. #R 137 18 105 9 133 10 108 11 115 12 170 13 103 14 IL |Obs. # |R 116 145 15 118 75 78 16 103 96 107 17 |111 123 122 184 18 104 135 103 148 19 111 112 | 116 147 120 89 193 107 187 121 178 176 1.
