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 18 trials of this experiment: 271, 186, 202, 250, 231, 257, 171, 175, 285, 269, 296, 236, 241, 217, 273, 229, 222, 311 Find 25th and 80th percentiles for these reaction times.
