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 0.02 significance level to test the claim
that there is no difference between the reaction times of the right and
left hands.
