We are studying the waiting times arising from two queueing systems. Suppose we make 4 independent replications of both systems, where the systems are simulated independently of each other. replication system 1 system2 1 10 25 2 20 10 3 5 40 4 30 30 Assuming that the average waiting time results from each replication are approximately normal, find a two-sided 95% CI for the difference in the means of the two systems. - ANSWER- This is a two-sample CI problem assuming unknown and unequal variances. We have [-29.76, 9.76] This is sort of the same as Question 2, except we have now used common random numbers to induce positive correlation between the results of the two systems. Again find a two-sided 95% CI for the difference in the means of the two systems. - ANSWER- This is a paired-t CI problem assuming unknown variance of the differences. [-16.5, -3.5] [Show More]
