D. Recommendation to the Heart Break Hotel manager
To 09/05/2018
The manager
Hotel Heart Break
Optimization of average daily cost and overbooked rooms
The average daily cost of the Heart Break hotel was found to be $ 190.83. The number of overbooked rooms was kept at three. The average number of no shows per day for the hotel was between zero and five. A random data pattern of no show for the customers was noticed. An excel sheet (figure 2) has been generated for the purpose of analysing the effect of no shows on the daily average cost of the hotel. The cost model was re-evaluated by varying the number of overbooked rooms in the hotel. The average daily cost was noted for five different situations. It was discovered that the daily average cost reduced by dropping the number of overbooked rooms in the hotel. The minimum simulated average daily cost was found to be $ 58.33 for zero overbooked rooms. Hence reduction in the number of overbooked rooms was profitable for the hotel (Tse & Poon, 2017).

Answer 2
A. Regression model of Price on mileage
Figure 14: Regression model for Price on Mileage
The regression equation was where Y was the Price of second hand car and X was the mileage covered of those old cars. The negative coefficient of Mileage covered, implied that price of the old cars was inversely related to the total mileage covered by that car. The p value for the coefficient of regression, for mileage was less than 0.05. Hence, the regression model significantly explained the price of the old cars.
Regression model of Price on Age (years)
Figure 15: Regression model for Price on age
The regression equation was where Y was the Price of second hand car and X was the age of those old cars. The negative coefficient of age, implied that price of the old cars was inversely related to the total age of those cars. The p value for the coefficient of regression, for age was less than 0.05. Hence, the regression model significantly explained the price of the old cars.
Regression model of Price on Mileaage and Age (years)
Figure 16: Regression model for Price on age and mileage
The regression equation was where Y was the Price of second hand car, X was the total mileage covered and S was the age of the car. The negative coefficients of age and mileage implied that price of the old cars were inversely related to the independent variables. The p values for the coefficient of regression of age and mileage were greater than 0.05. Hence, the regression model was not able to significantly explain the price of the old cars based on age of the cars and total mileage travelled, when considered together. Individual regression models explained the variance of price of the cars, better than the combined model (Draper & Smith, 2014).
b. First two models were better than the combined regression model. The adjusted R square value was greatest in the second model. Thus age of the cars was able to expalin 69.75% variation of the price of old cars, and preference was reserved for the model. The p-values for the price-mileage model were also statistically significant and therefore that model was much more statistically significant than other models. Negative coefficients of age and mileage IN regression model implied that price of the old cars were inversely related to the independent variables. The relation between price and total mileage covered, age of the car was obvious in nature (Chatterjee & Hadi, 2015).
c.
Correlation between the independent variables, Mileage and Age
Figure 17: Correlation matrix for the two independent variables
Mileage and age of the cars were highly (positively) correlated. Hence validity score was checked for the independent variables. Selection of both the variables as independent factors was advised.
Answer 3:
Model setup and solver solution
The initial model setup with 200 numbers of sold units has been provided in figure 18 (left table). The excel solver solution with break even zero profit also has been provided in figure 18 (right table) (Ku & Nor, 2016)
Figure 18: Initial and solver setup for profit
B. The initial model was solved by excel solver for $ 1600 profit, to obtain number of units sold as 500 units. Figure 19 describes the model.
Figure 19: solver setup for profit of $ 1600
C. Two products namely A and B were set up in the initial model with number of units as 200 and 100 (2:1 ratio). The total profit was found by the sum of the profits for both the products, A and B. excel solver was used to acheive the profit of $ 20,000 in P column by changing the number of units. The solver solution has been provided in figure 20 (right table) (Anderson & Leese, 2016).
