Question
The manager of a hotel chain is interested in knowing whether there is a relationship between the number of positive reviews a hotel receives online and its occupancy rate. The manager collected data from 10 hotels and recorded the number of positive reviews each hotel received on a popular travel website and the corresponding occupancy rate (in percentage) for the same period. The data is shown below: 45 65 55 80 75 70 90 50 60 85 Hotel Positive Reviews 72 82 78 89 86 81 92 76 77 88 Occupancy Rate% 1. Determine the dependent and independent variables. 2. Calculate the correlation coefficient and comment. 3. Determine the regression equation Ŷ = a + bx. 4. Give a brief interpretation for the values of "a" and "b". 5. If the hotel had no positive reviews, what would the occupancy rate be?
