In a study designed to predict blood cholesterol levels from amount of daily saturated fat in grams (X₁) and number of hours of daily exercise (X₂), the slope of X₁ is 5, the slope of X₂ is -4, and the y intercept is 130.Which formula is the regression equation for these data? A) Ŷ = 130 + 5(X₁) - 4(X₂) B) Ŷ = 130 - 4(X₁) - 5(X₂) C) Ŷ = 130 + 5(X₁) + 4(X₂) D) Ŷ = 130 + 1(X)

The regression equation is Ŷ = b0 + b1(X₁) + b2(X₂), where b1 is the slope of X₁, b2 is the slope of X₂, and b0 is the y-intercept. Plugging in the given values, we get Ŷ = 130 + 5(X₁) - 4(X₂).
