Answer :
A multiple linear regression model would allow us to predict overall scores based on 'Shore Excursions' and 'Food/Dining' scores. The form of equation would be Y = a + b*X1 + c*X2, where b and c are coefficients obtained from the regression analysis. Actual computation, however, requires the full dataset and appropriate statistical software.
In order to predict the overall score using independent variables 'Shore Excursions' and 'Food/Dining', we need to build a multiple linear regression model.
This data analysis technique is used to explain the relationship between one dependent variable and two or more independent variables.
In this case, we will use 'Shore Excursions' and 'Food/Dining' as independent variables and 'Overall Score' as the dependent variable.
The general form of the model is Y = a + bX1 + cX2 where, Y represents the dependent variable, a is the y-intercept, b and c are the coefficients of the independent variables X1 and X2 respectively.
The coefficients b and c estimate the change in overall score for each unit increase in the Shore Excursions and Food/Dining scores, given that the other variable is held constant.
However, without the actual dataset or the statistical software, it's impossible to perform the regression analysis and establish the estimated regression equation.
Therefore, Unable to predict the overall score given the scores for 'Shore Excursions' and 'Food/Dining' specifically for a Shore Excursions score of 80 and Food/Dining score of 90.
