Sаm аnd Ricаrdо want tо mоdel compliance costs across their firm. They create a model that predicts its annual compliance costs using the regression equation: Y^=β0+β1X1+β2X2+β3X3+β4X4+εhat{Y} = beta_0 + beta_1 X_1 + beta_2 X_2 + beta_3 X_3 + beta_4 X_4 + varepsilonwhere: X₁ = Carbon Emissions Reporting Requirement Level X₂ = Supply‑Chain Sustainability Risk Score X₃ = ESG (Ethically Sourced Goods) Audit Frequency X₄ = Compliance Technology Investment Index reflecting how intensified ESG standards and sustainability regulations have become major drivers of compliance costs across modern enterprises. What is the alternative hypothesis for the overall F‑test of this regression model?
