Question 7 {10 pts} Do Good Smells Bring Good Business (dataset odors.csv)? Businesses know that customers often respond to background music. Do they also respond to odors? Nicolas Guguen and his colleagues studied this question in a small pizza restaurant in France on Saturday evenings in May. On one evening, a relaxing lavender odor was spread through the restaurant; on another evening, a stimulating lemon odor; a third evening served as a control, with no odor. The data below {Table 2.2 in the textbook) shows the amounts (in euros) that customers spent on each of these evenings: Ho Odor 15.9 18.5 15.9 18.5 18.5 21.9 15.9 15.9 15.9 15.9 15.9 18.5 18.5 18.5 20.5 18.5 18.5 15.9 15.9 15.9 13.5 18.5 15.9 13.5 15.9 18.5 15.9 25.5 12.9 15.9 Lemon Odell 18.5 15.9 13.5 18.5 18.5 15.9 18.5 15.9 18.5 13.5 15.9 18.5 2L5 1.5.9 2.1.9 15.9 18.5 18.5 18.5 18.5 25.9 15.9 15.9 15.9 18.5 18.5 18.5 18.5 Lmndor Odor 21.9 18.5 22.3 21.9 18.5 24.9 18.5 22.5 21.5 21.9 21.5 18.5 25.5 18.5 18.5 21.9 18.5 18.5 24.9 2L9 25.9 21.9 18.5 18.5 22.8 18.5 21.9 20.? 21.9 2.5 Give a graphical comparison of the three distributions using side-by-side boxplots. Provide appropriate numerical summaries for the three distributions and identify any outliers in each group.
