Ryan works for a country that is researching and modeling trade policy. He creates a model to predict monthly operating costs using the regression equation: Y^=220.5+4.75X1+3.12X2+1.88X3−2.45X4\hat{Y} = 220.5 + 4.75X_1 + 3.12X_2 + 1.88X_3 – 2.45X_4 where X₁ = Tariff Rate (%), X₂ = Supply Chain Disruption Index, X₃ = Fuel Price Index, X₄ = Inventory Buffer Level, What is the alternative hypothesis for the overall F‑test of this regression model?
