Several students were tested for reaction times(in thousandths of asecond) 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 thesubject.) Results from five of the students are included in the graph to the right. Use a 0.10 significance level to test the claim that there is no difference between the reaction times of the right and left hands. Find the null and alternative hypothesis, test statistic, critical values, and conclusion.
