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 Obs.# R L L Obs.# R 1 113 8 116 166 22 100 2 105 105 9 75 146 23 89 3 130 133 10 96 123 24 85 4 101 108 11 122 135 25 88 5 138 115 12 103 6 118 170 13 116 7 87 103 14 107 At 1% level of significance, can we conclude that these right-handed students found it easier to use the knobs with a right-hand thread?
