A regression analysis was performed to study the relationship between a dependent variable and four independent variables. The following information was obtained:
r² = 0.95, SSR = 9800, n = 50.
ANOVA $$\begin{array} { | l | r c c c | } \hline \text { Source of Variation } & d f & \text { SS } & M S & F \\\hline \text { Regression } & 4 & 9800 & 2450 & 50.114 \\\text { Error } & 45 & 2200 & 48.889 & \\\hline \text { Total } & 49 & 12,000 & & \\\hline\end{array}$$ Test the overall validity of the model at the 5% significance level.
