I need these questions answered

In an experiment conducted online at the University of Mississippi, study participants are asked to react to a stimulus. In one experiment, the participant must press a key on seeing a blue screen and the reaction time (in seconds) to press the key is measured. The same person is then asked to press a key on seeing a red screen, again with reaction time measured. The results for six randomly sampled study participates are as follows: Participant 2 3 4 5 6 Blue (X;) 0.620 0.501 0.845 0.323 0.685 .450 Red (Yi) 0.408 0.407 0.542 0.402 0.456 0.533 Create a 99% confidence interval for the difference in reaction time.
