(nd). The ANOVA table shows the result of the ANOVA analysis and whether there is a statistically significant difference between the group means. We can see that the significance level for Att is 0.00 and 0.827 for Attnew. When this value is less than 0.05 it means that there is a significant difference between the two means. When it is greater than 0.05 the statistical difference between the two means is zero or minimal. So for Attnew, there is a difference in the demand for cars but there is no difference in the Att case (Hussain, M. (n.d.)).Multiple Regressions“Multiple regression is an extension of simple linear regression. It is used when we want to predict the value of one variable based on the value of two or more other variables. The variable we want to predict is called the dependent variable (or sometimes the outcome, goal, or criterion variable). The variables that we use to predict the value of the dependent variable are called independent variables (or sometimes predictor, explanatory, or regressor variables). The output of the multiple regression helps determine the fit of the model and facilitates making a legal decision
