In a multiple regression analysis involving 6 independent variables and a sample of 19 data points the total variation in y is SS_y = 900 and the amount of variation in y that is explained by the variations in the independent variables is SSR = 600. The value of the F-test statistic for this model is: A) 4.0. B) 4.3. C) 4.8. D) 6.3.

The F-test statistic is calculated as (SSR/k) / (SSE/(n-k-1)), where k is the number of independent variables and n is the sample size. Here, SSR = 600, SSE = SSy - SSR = 300, k = 6, and n = 19. So, F = (600/6) / (300/(19-6-1)) = 4.0.
