Use the fоllоwing infоrmаtion to аnswer Questions 2-4. The formulа sheet is here: Formula sheet_Midterm.pdf A grocery store has two checkout counters. Each counter can serve 5 customers per hour on average. It is estimated that a customer completes the purchase and needs to check out every 15 min on average. Assume that the inter-arrival time and the service time follow exponential distribution. Constrained by the layout of the grocery store, the manager requires customers to form two separate lines with each one dedicated to a checkout counter. This means that a customer in one line can only be served by the counter for that line. To reduce customers’ average waiting time, the manager should do which of the followings?
