The average number of accidents is a descriptive statistic that describes a characteristic of a population (in this case, the city's total number of accidents). Statistical inference would involve drawing conclusions about the population based on a sample, which is not relevant here. The concept of a sample or population also does not apply in this context, since the entire population (all accidents in the city) is being examined.
