Rоund аnswers tо three decimаl plаces. A randоm sample of experienced drivers participated in a simulator study to assess reaction time under two different lighting conditions. Each driver completed the same driving course twice—once during simulated daylight and once during simulated nighttime conditions. For each participant, the order in which they experienced the conditions was randomly determined. The reaction time (in seconds) to unexpected obstacles for each person was recorded for each condition. The data is summarized below. Difference n mean standard deviation daylight - nighttime 28 0.845 1.572 Determine the 90% confidence interval to estimate the mean difference in reactions times under the two conditions: ([lower], [upper]) What is the margin of error for your interval?
