A particular bank typically has three tellers available on Friday afternoons. When a single line is formed, so that the next available teller serves the next person in line, the wait times are 4 minutes, 7 minutes, and 7 minutes. When three separate lines are formed, one for each teller, the wait times are 1 minute, 3 minutes, and 14 minutes. Find the mean for a single line. Round to two decimal places, if necessary. (You should only type the number, not the units.) 6 . A particular bank typically has three tellers available on Friday afternoons.

When three separate lines are formed, one for each teller, the wait times are 1 minute, 3 minutes, and 14 minutes. Find the standard deviation for a single line.

As the bank manager, would you rather have a single line or multiple lines? Please note that in both situations, there are three tellers helping customers. With a single line, the next person in line will go to the next available teller; like at the U-Scan self-checkout lines of a grocery store. With multiple lines, customers will line up behind the cashier of their choice; like “normal” grocery store lines. Multiple lines or Single line 10. Defend your answer to Question #9. Why would you prefer the line structure that you chose? Note – With either line structure, there are three tellers. A single line structure is like the self-scan lines at the grocery store. There may be six scanners, but everyone forms one line. The next person in line goes to the next available scanner. With multiple-lines, people will line up behind the teller they want to help them, such as the “regular” lines at the grocery store
