An experiment was conducted to compare people's reaction time in seconds to a red light versus a green light. The following results give the reaction times for eight subjects. Determine at 0.05 level of significance if there is any difference in reaction to the two lights when same eight subjects are observed for the test. Also find the 95% confidence interval for difference in mean reaction time. 452 1 46 Red Green 5 10 4 8 3 24 3 5 4
