This is demonstrated by the ANOVA value in the tables above. Accepting this regression model might be wise, for instance, if the value of F (significance) is smaller than alpha, or.05. Here, 7.25547E-05, the significance factor, is less than alpha. This number indicates a p-value of 0.0002835 and a beta coefficient of 107.04 for age. This demonstrates how cost and age relate to one another can have important consequences (Wang et al., 2019). A p-value of 0.14987 and a beta value of -9.19469 are displayed when viewing the satisfaction beta value. The association between the independent and outcome variables (cost) is negative, as indicated by the negative value, while the p-value is positive. The variable in this instance therefore has no significant link with, as indicated by a larger p-value than the alpha value.
