Suppose you are an employee with the Ministry of Transport

Suppose you are an employee with the Ministry of Transport. The Ministry is interested in determining whether significant road maintenance is necessary on a particular stretch of road. In addition to assessing current damage to the road, the ministry would like an accurate understanding of the frequency with which the road is used, and they give you the task of figuring this out. You set up a camera to record passing vehicles for an entire year, and find that on average, 110 vehicles pass the camera per day, with a standard deviation of 4 vehicles. Let X = the number of vehicles that pass the intersection per day.
