February 16, 2024 at 2:27 PM Suppose we are interested in the mean speed of vehicles on interstate highways in the U.S. We checked the speed of 40 cars near exit 115 on the l-45 and the result is as below (in mph): 80, 75, 65, 70, 73, 72, 79, 73, 75, 77, 80, 75, 65, 70, 73, 72, 79, 73, 75, 77, 80, 75, 65, 70, 73, 72, 79, 73, 75, 77, 80, 75, 65, 70, 73, 72, 79, 73, 75, 77. Find the upper bound of a 95% confidence interval for the true mean speed of vehicles on interstate highways in the U.S. (Answer in 3 decimals.)
