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
