Q1
A grocery chain began playing slower-tempo music in its stores and found that average customer time in-store increased by 12%. During the same period, the chain also rearranged aisle layouts, placing frequently purchased items farther apart. Because layout changes can force customers to walk more and thus spend more time in the store, the chain concludes that the music change had little effect on time in-store; the new layout explains the increase. Therefore, if the chain reverts to the old layout while keeping the slower music, customer time in-store will return to its previous level. The answer to which one of the following questions would be most helpful in evaluating the argument?
