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

What are the hypotheses for this test?
Let u, be the
mean of the differences
of the right and left hand reaction times.
Ho: Hd = 0
H: Ho # 0
What is the test statistic?
t= -3.163 (Round to three decimal places as needed.)
