| Question 14 |
Which of the following statements are FALSE?
| For poisson distribution, the mean is twice the variance. | |
| In queuing theory, if arrivals occur according to poisson distribution, then the inter-arrival time is exponentially distributed. | |
| The distribution of waiting time is independent of the service discipline used in selecting the waiting customers for service. | |
| If the time between successive arrivals is exponential, then the time between the occurrences of every third arrival is also exponential. | |
| Both (A) and (C). |
Question 14 Explanation:
In Poisson distribution, the mean is not equal to the twice the variance.
Option C is also False, because waiting time is dependent on the service discipline.
Option C is also False, because waiting time is dependent on the service discipline.
