You have the job of estimating the mean speed of vehicles in the northbound lanes of IGSW at the University Avenue overpass between 4:00 and 4:30 in the afternoon on weekdays {i.e. at the beginning of rush hour]. To accomplish thisjob you are going to stand on the University Avenue overpass with a radar gun and take speed measurements of the trafc in the northbound lanes of I35W. The question addressed in this problem is: how many measurements do you need to take?r Numerous studies in comparable setting shows that the standard deviation of speeds is about 5 [mph]. You can accept only a 5% chance of getting an estimation error greater than 1 [mph]. Approximately how many individual speed measurements are required
