When estimating the equation Home Price = Bo + Bift² house + B₂ft²lot + 33 Bedrooms + B. Bathrooms + e, which of the following could we say about ₁? (a) B₁ will likely be positive because large houses typically have more bedrooms, which consumers are willing to pay more for. (b) ₁ will likely be positive because consumers pay more for bigger houses. (c) B₁ will likely be positive because big house tend to be on big lots. (d) All of the above
