Question 10 く Suppose that we are studying the amount of time customers wait in line at the checkout at the Gap and Old Navy. The avérage wait time at both stores is five minutes. At the Gap, the standard deviation for the wait time is 2 minutes; at Old Navy the standard deviation for the wait time is 5 minutes. Because Old Navy has a higher standard deviation, we know that there is Select an answer v in the wait times at Old Navy. Overall, wait times at Old Navy are Select an answer v from the average; wait times at the Gap are Select an answer v near the average.
