A cоmpаny exаmines the relаtiоnship between sales (Y), advertising budget (X₁ in $1000s), and stоre size (X₂ in 100 sq ft). They run three models: Model 1: Y = β₀ + β₁X₁ Model 2: Y = β₀ + β₁X₁ + β₂X₂ Model 3: Y = β₀ + β₁X₁ + β₂X₂ + β₃(X₁·X₂) Results: Model 1: R² = 0.45, Adjusted R² = 0.44, β₁ = 2.5 Model 2: R² = 0.65, Adjusted R² = 0.63, β₁ = 1.8, β₂ = 3.2 Model 3: R² = 0.82, Adjusted R² = 0.80, β₁ = 0.5, β₂ = 1.1, β₃ = 0.6 Which of the following statements are true?
