Extracted text: 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 fallowing list contains the reaction times (in milliseconds) for the 16 trials of this experiment: 241, 271. 261, 164, 257, 193. 186, 222, 226, 212, 152, 273, 217, 171, 175, 202 Send date to caleulator Find 40 and 75" percentiles for these reaction times. (a) The 40 percentile: Imilliseconds (b) The 75t percentile: miliseconds
