2a)Consider the grocery store with one check out counter. Prepare the simulation table for eight customers and find out average waiting time of customer in queue,idle time of server and average service time .The inter arrival time (IAT) and service time (ST) are given in minutes.
IAT : 3,2,6,4,4,5,8
ST(min) :3,5,5,8,4,6,2,3
Assume first customer arrives at time t=0
