Post-Lab Homework Problems. 1. A student is using a track photogate to determine the time it takes her to run 50 meters. She records the following times: Trial Time (seconds) 1 5.420 5.464 3 5.728 4 5.496 5 5.644 6. 5.794 7 5.540 The data she collects has a mean of 5.583714 seconds, with an absolute uncertainty computed to be 0.141074 seconds. Report her 50-meter time as a confidence interval (a) using the mean and the absolute uncertainty given above. Another student measures his 200-meter run time (b) to be 20.7 + 0.3 seconds. Report the relative uncertainty of each student and identify which has the more precise run time.
