Consider a hypothetical experiment on reaction time (the time it takes to push a button in response to a signal). One group is given a simple reaction time task (a light comes on and they push the button). A second group is given a choice reaction time task (an "A" or a "B" is presented and the subjects push one button for "A" and a different button for "3"). Assume that it is known that reaction times are normally distributed, and that the standard deviation for the simple reaction time task is 80 milliseconds and the standard deviation for the choice reaction time task is 110 milliseconds. Seven subjects are tested with the simple reaction time task and eight subjects with the choice reaction time task. Their scores (in milliseconds) are shownlbelow: Simple RT: 205, 230, 284, 320, 390, 370, 245. Choice RT: 300, 316, 380, 410, 502, 570, 360, 490. Estimate the difference between simple and choice reaction time by computing the 95% condence interval on the difference "simple choice". [Note: Enter the two endpoints of the condence interval, the lower endpoint first, and the upper endpoint second, both rounded to three decimal places. Keep in mind that both numbers will be negative. ] gr 6/
