A spare part is demanded infrequently, with the average time between demands being

$6$

$$weeks$.$ Previous analysis has shown that the time between demands follows a negative exponential distribution.

Simulate the next interarrival times, using the following stream of random numbers, starting at the leftmost number, and using fourdigit random numbers:

$-$

$-$

$9$

$0$

$4$

$2$

$0$

$7$

$4$

$5$

$0$

$5$

If a part has just been demanded, what is your simulated arrival time for the demand for the next part?
