You are interested in examining the factors that determine the average length of stay in a hospital across provinces. You collect data on the following variables:
Y = province-wide average hospital stay
X₂ = median provincial income
X₃ = 1 if the province is one of the Atlantic provinces, 0 otherwise
X₄ = 1 if the province is in Quebec or Ontario, 0 otherwise
X₅ = 1 if the province is in the Prairies, 0 otherwise
X₆ = 1 if the province is BC or Alberta, 0 otherwise

You run the following regression Y = β₁ + β₂X₂ + β₃X₃ + β₄X₄ + β₅X₅. How much longer would we expect to stay in a hospital in the Atlantic provinces than in a hospital in Ontario or Quebec?

A. β₃
B. β₁ + β₃
C. β₃ - β₄
D. β₄
