Several students were tested for reaction times (inthousandths of a second) using their right and lefthands. (Each value is the elapsed time between the release ofa strip of paper and the instant that it is caught bythe subject.) Results from five of the students are includedin the graph to the right. Use a 0.10 significance level to testthe claim that there is no difference between the reaction times ofthe right and left hands.
