Waiting times (in minutes) of customers in a bank where all customers enter a single waiting line and a bank where customers wait in individual lines at three different teller windows are listed below. Find the mean and median for each of the two samples, then compare the two sets of results. Single Line 6.4 6.6 6.7 6.8 7.1 7.2 Individual Lines 7.5 7.8 7.8 7.8 4.2 5.2 5.9 6.2 6.5 7.8 7.8 8.6 9.5 10.0 The mean waiting time for customers in a single line is 7.17 minutes. The median waiting time for customers in a single line is 7.15 minutes. The mean waiting time for customers in individual lines is 7.17 minutes.
