Four students all do the same experiment for the science fair. They test reaction times for pushing a button when a specific color is shown. Their data is as follows: student 1: 0.44(trial one) 0.41(trial two) 0.47(trial three) 0.39(trial four) 0.46(trial five) 0.42(trial six)
student 2: 0.35(trial one) 0.43(trial two) 0.38(trial three) 0.39(trial four) 0.42(trial five) 0.44(trial six)
student 3: 0.41(trial one) 0.52(trial two) 0.57(trial three) 0.46(trial four) 0.55(trial five) 0.49(trial six)
student 4: 0.42(trial one) 0.43(trial two) 0.41(trial three) 0.42(trial four) 0.41(trial five) 0.42(trial six)
