Which one of the following statement about linear multiple regression is correct? O a. In testing the significance of a multiple regression model with three independent variables, the null hypothesis is Ho: B1 = B2 = B3. O b. A multiple regression equation has a coefficient of determination of 0.81. Then, the percentage of the variation in y that is explained by the regression y equation is 90%. O c. To test the significance of a multiple regression model involving 4 independent variables and 25 observations, the numerator and denominator degrees of freedom for the critical value of Fare 3 and 21, respectively. - O d. In a multiple regression analysis involving 50 observations and 5 independent variables, the total variation in y is 475 and SSE = 71.25. Then, the coefficient of determination is 0.85. Oe. None of the suggested answers are correct.
