If you were the manager, which option would you select? Why? Explain the disparity between the results for the two options What assumptions did you make in your analysis?

The operations manager of a soon-to-open branch of a large bank is in the process of configuring teller operations. Currently some branches have a separate teller line for customers who have a single transaction, while other branches do not have separate lines. The manager wants to avoid complaints about long waits that have been received at some branches. Because the demographics differ from location to location, a system that works at one branch will not necessarily work at another. The manager has obtained data on processing times from the bank’s home office, and is ready to explore different options for con-figuring operations.
