2. A market researcher is interested in the effects of music on shopping behavior. The researcher believes that if
participants are exposed to slow-paced music, they will be likely to linger in a store longer and are more likely to buy
more products. Participants exposed to fast-paced music will not stay in the store as long and will not buy as many
products. To test this, the researcher has access to all the supermarkets in a medium-sized Midwestern town. For 3
months, the researcher has the stores play fast-paced music. The researcher records the total amount of sales for the 3
months. At the end of the 3 months, the researcher has the stores switch to slow-paced music. The researcher records the
amount of sales for this second 3 month period. The researcher found that sales were higher when the slow-paced music
was played than when the fast-paced music was played.
