Question

The table below shows the Excel output for a multiple regression model for 8 observations of two independent variables. 1. Write the multiple regression equation for the relationship between the dependent variable y and the independent variables x_1 and x_2; A) y = 30 + 16x B) y = 83.23 + 2.29x_1 + 1.30x_2 C) y = 50 + 2.29x_1 + 12.6x_2 Which of the following statements is true: A) The value of the y variable is increasing by 2.29 for each unit increase in variable x_2. B) The value of the y variable is decreasing by 1.30 for each unit increase in variable x_2. C) The value of the y variable is increasing by 2.29 for each unit increase in variable x_1. D) The value of the y variable is increasing by 50 for each unit increase in the intercept. The multiple coefficient of determination is: A) 0.87 B) 0.76 C) 0.99 D) 0.92 The adjusted multiple coefficient of determination is: A) 0.89 B) 0.95 C) 0.76 D) 0.99 The predicted value of y when x_1 = 10 and x_2 = 2 i
