1. A BOA branch and a Chase branch located in a commercial district of a city have the business objective of developing an improved process for serving customers during the noon-to-1:00 pm lunch period. The waiting time, in minutes, is defined as the time the customer enters the line to when he or she reaches the teller window. Data collected from a sample of 15 customers during this hour for each bank are stored in the spreadsheet Bank Waiting Time.xlsx (attached picture).
