Score: 0 of 1 pt 4 of 16 (7 complete) HW Score: 27.08%, 4.33 of 16 pts 9.4.10-T Question Help * 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 0.01 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. 100 150 Right Hand What are the hypotheses for this test? rrect: 1 Let d be the | of the right and left hand reaction times Click to select your answer(s) and then click Check Answer. Answer Clear All

Explanation / Answer

Here ud is the mean of the difference of right and left hand reaction time.

Here our claim is there is no difference between the reaction time of right and left hand of reaction.

That is ud not equal to 0.(ud=/ 0)

So H0:ud = 0 (hypothesis of no difference)

H1:ud =/0 (opposite to the null hypothesis)
