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 0.20 significance level to test the claim that there is no difference between the reaction times of the right and left hands. Right Hand Left Hand     112 134     124 135     140 159     168 184     197 211
