Waiting times (in minutes) of customers at a bank where all customers enter a single waiting line and a bank where customers wait in in three different teller windows are
listed below. Find the coefficient of variation for each of the two sets of data, then compare the variation
Bank A (single line): 6.4 6.7 6.8 6.8 71 72 7.4 77 77 78 0
Bank B (individual 42 53 5.9 62 66 77 78 8.5 9 2 9.7
The coefficient of variation for the waiting times at Bank A is %
(Round to one decimal place as needed.)
