Question

A certain bridge in Cebu is being re-constructed. The civil engineers would like to consider the number of heavy-duty vehicles that pass through that certain bridge in re-designing. The industrial engineers are tasked to do the job in finding the probability that certain number of heavy-duty vehicles pass through the bridge in a specific period of time. The IEs collected the data below. The IE would like to know if queuing theory is applicable in simulating the number of heavy-duty vehicles that pass through the bridge. One condition of using queuing theory is that the data must be Poisson distributed. Test at 1% level of significance if the data is collected by the IE is Poisson distributed.

duty vehicles that
