On each trial of an experiment, a subject is presented with a constant soft noise, which is interrupted at some unpredictable time by a noticeably louder sound. The time it takes for the subject to react to this louder sound is recorded. The following list contains the reaction times (in milliseconds) for the 17 trials of this experiment: 212, 171, 164, 229, 175, 296, 217, 226, 193, 273, 311, 285, 236, 186, 261, 250, 235 Send data to calculator Find 10th and 75th percentiles for these reaction times. (If necessary, consult a list of formulas.)
