Question

Select True or False from each pull-down menu, depending on whether the corresponding statement is true or false For the multiple regression model y^circ = 40 + 15x_1- 10x_2 5x_3 if x_2 were to increase by 5 units, holding x_1 and x_3 constant, the value of y would decrease on average by 50 units A multiple regression model has the form y^circ = 6.75 + 2.25x_1 +3.5x_2 As x_1 increases by 1 unit, holding x_2 constant, then the value of y will increase by 9 units. In order to test the significance of a multiple regression model involving 5 independent variables and 30 observations, the numerator and denominator degrees of freedom for the critical value of F are 5 and 24, respectively. In a multiple regression analysis involving 50 observations and 5 independent variables, SST = 475 and SSE = 71.25. The multiple coefficient of determination is 0.85.

Explanation / Answer

1) True

2) False

3) True

4) True ( since formula = 1 - (sse/sst) = 1 - 0.15 = 0.85)
