An experiment was conducted to compare people’s reaction times to a red light versus a green light. When signaled with either the red or the green light, the subject was asked to hit a switch to turn off the light. When the switch was hit, a clock was turned off and the reaction time in seconds was recorded. The following result gives the reaction times for eight subjects. Find a 90% confidence interval for the mean difference of the reactions in the populations.
