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 in seeing a blue screen. 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 the reaction time measured The results for six randomly selected participants are as follows Is there evidence at the a alpha = 0.01 level that the reaction time is different between red stimuli?
