You are interested in examining the factors that determine the average length of stay by patients in hospitals 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 the state is in the Midwest,0 otherwise
X₅ = 1 the state is in the West,0 otherwise
Based on the data above,you run the following regression: Y = β₀ + β₁X₁ + β₂X₂ + β₃X₃ + β₄X₄.
Identify the length of stay for each of the four regions using the population slopes.
