12.9 Ambiance of 5-star hotels. Although invisible and in-
tangible, ambient conditions such as air quality (x1),
temperature (x2), odor/aroma (x3), music (x4), noise
level (x5), and overall image (x6) may affect guests'
satisfaction with their stay at a hotel. A study in the
Journal of Hospitality Marketing & Management (Vol. 24,
2015) was designed to assess the effect of each of these
ambient factors on customer satisfaction with the hotel (y).
Using a survey, researchers collected data for a sample of
422 guests at 5-star hotels. All variables were measured
as an average of several 5-point questionnaire responses.
The results of the multiple regression are summarized in
the table on the next page.
a. Write the equation of a first-order model for hotel
image (y) as a function of the six ambient condi-
tions.
