Do good smells bring good business? Businesses know that customers often respond to background music. Do they also respond to odors? Nicolas Guéguen and his colleagues studied this question. in a small pizza restaurant in France on Saturday evenings in May. On one evening, a relaxing lav- ender odor was spread through the restaurant; on another evening, a stimulating lemon odor; a third evening served as a control, with no odor. The three evenings were comparable in many ways (weather, customer count, and so on), so we are willing to regard the data as independent SRSs from spring Saturday evenings at this restaurant. Table 27.4 contains data on how long (in minutes) customers stayed in the restaurant on each of the three evenings. 18 ODORS (a) Make an appropriate graph comparing the customer times for each evening. Do any of the distributions show outliers, strong skewness, or other clear deviations from Normality? (b) Do a complete analysis to see whether the groups differ in the average amount of time spent in the restaurant. Follow the four-step process in your work.
