A group of researchers wants to do a comparative study on auditory reaction time (ART) and visual reaction time (VRT) of Visual Arts majors. They took a sample of twenty college students who majored in Visual Arts, and each was given a unique serial number. In their study, two tasks were administered: (1) a VRT task where they need to press the spacebar of the computer keyboard once a red dot appears on the screen and (2) an ART task where a 20-second sound will be played, and the participants need to press the spacebar once the sound is presented. A randomization mechanism was done to determine which task would be administered first. The tables of the reaction times are shown below: Visual Task Reaction Time 1.37 Auditory Task Reaction Time Student Student 1 1 1.13 1.05 1.05 3 1.33 3 1.30 4 1.08 4 1.01 5 1.15 1.38 6 1.10 6 1.18 7 1.03 7 0.87 8 1.45 8 1.16 9 0.78 9 0.75 10 1.07 10 0.98 11 0.84 11 1.22 12 1.34 12 1.03 13 1.47 13 1.16 14 0.97 14 1.07 15 1.66 15 1.18 16 0.76 16 0.78 17 1.16 17 1.00 18 0.78 18 0.89 19 1.09 19 0.85 20 1.23 20 0.83 Is there sufficient evidence to conclude that Visual Arts majors perform better in the VRT task than in the ART task? Test at 0.05 level of significance.
