Suppose that the performance measure you are interested is the long$-$run average number of

customers in a certain queue. Which of the followings is true about the appropriate output

analysis? Choose only one.

a$)$ The ending simulation time is well defined.

b$)$ If the batch size is taken too small $($than what it should be$),$ the length of the computed

confidence interval will typically be smaller than what it should be$.$

c$)$ When there is high dependency between within replication data, we have to increase the

number of replications to improve the estimation precision.

d$)$ If the method of batch means is used, and batch means turn out to be dependent, one

should increase the warm$-$up period.
