THE NEXT QUESTIONS ARE BASED ON THE FOLLOWING INFORMATION

THE NEXT QUESTIONS ARE BASED ON THE FOLLOWING INFORMATION:
You are interested in examining the factors that determine the average length of stay in a hospital across states.You collect data on the following variables:
Y = statewide average hospital stay
X₁ = median state income
X₂ = 1 if the state is in the Northeast,0 otherwise
X₃ = 1 if the state is in the South,0 otherwise
X₄ = 1 if the state is in the Midwest,0 otherwise
X₅ = 1 if the state is in the West,0 otherwise
-You run the following regression Y = β₀ + β₁X₁ + β₂X₂ + β₃X₃ + β₅X₅.How much longer would we expect to stay in a hospital in the Northeast than in a hospital in the Midwest?

A) β₀
B) β₀ + β₅
C) β₂
D) β₀ - β₄
