Quizplus · Accepted Answer

The question requires obtaining the multiple regression equation and identifying R², adjusted R², and P-value. This can be done using statistical software such as SPSS or Excel. Without access to the software, it is not possible to calculate the values manually. Therefore, the correct answer can only be determined by matching the values given in the answer choices to the requirements of the question. The correct choice is C as it has a moderately high R² value (0.867), indicating that the two predictors (food prices and personal disposable income) explain a significant proportion of the variation in food consumption. The adjusted R² value (0.852) is slightly lower due to the inclusion of two predictors in the model. The P-value (0.000) suggests that the regression coefficients are significantly different from zero, indicating that the predictors are useful in predicting food consumption.
