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. Click the icon to view the reaction time data table.

Question
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.
