Need type answer a. A section of road has 55 accidents recorded in three years. For the same period, the estimated vehicle travel on the section was 23 mvk. Considering only those sections having the same characteristics as the section under study, the mean rate is 80 accidents per 100 mvk. Is the section hazardous with 90 percent level of confidence? b. Based on the graph of the accidents time per day on ‘explain’, what time makes up the most number of accidents? Discuss and explain why the frequency of accident is high.
