For the M/M/1 queueing model, why do the following results hold? (Hint: Remember that 1
is the mean service time. Then think how long a typical arrival must wait in the system or in the queue.)


a. W = (L + 1)


b. W_Q
= L

Work the previous problem when the demands are positively correlated, as they might be with products such as peanut butter and jelly. Now use p = 0.3, p = 0.5, and p = 0.7 in your simulations.
