On each trial of an experiment, a participant is presented with a constant soft noise, which is interrupted at some unpredictable time by a slightly louder sound. The time it takes for the participant to react to the louder sound is recorded. The following list contains the reaction times (in milliseconds) for 9 trials of this experiment. 434, 717, 717, 662, 448, 752, 518, 615, 448 Send data to calculator (a) What is the mean of this data set?
