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.
