17. There's а stereоtype thаt Eurоpeаns give lоw tips in restaurants. One predicted consequence of this stereotype is that servers in American restaurants may be less friendly toward their European customers compared to their American customers. You design a field experiment to test whether this is true. You have a friend who is good at faking accents, and you pay her to go out to 10 restaurants around Madison. In half of the restaurants she goes to, you have her speak with an American accent; in the other half, you have her speak with a French accent. At each restaurant, you have your friend jot down whether she is speaking in an American or French accent; to measure the friendliness of the server, you also have your friend jot down how often the server smiles at her. Please answer the following: 1) Is an experiment an appropriate method for this study? Why or why not? 2) Once your friend has finished eating at all 10 restaurants, she gives you the information she jotted down. When she spoke with an American accent, the waiter smiled at her an average of 7.6 times; when she spoke with a French accent, the waiter smiled at her an average of 8.2 times. Is there evidence to support the initial prediction? 3) Describe one strength of the study design. 4) Describe one weakness of the study design.
