1. Assume SSE = 18, SSTO = 90, MSE = 6 and F* = 2. How many populations are there in the ANOVA analysis?
2. In a multiple regression model with n = 12 and 3 independent variables, the total sum of squares is 640 and SSR = 380. The standard error of the estimate is _____________.

B. No linear relationship exists between Y and either of the independent variables
C. All of the regression coefficients are equal to zero
D. There is a linear relationship between Y and both independent variables
