question 72

Multiple Choice

Consider the following regression model: Humidity = β₀ + β₁Temperature + β₂Spring + β₃Summer + β₄Fall + β₅Rain + ε, where the dummy variables Spring, Summer, and Fall represent the qualitative variable Season (spring, summer, fall, winter) , and the dummy variable Rain is defined as Rain = 1 if rainy day, Rain = 0 otherwise.
What is the regression equation for the summer days?

• A) = (b₀ + b₃) + b₁Temperature + b₅Rain
• B) = b₀ + b₁Temperature + b₅Rain
• C) = b₀ + b₁Temperature + b₂Spring + b₅Rain
• D) = b₀ + b₁Temperature + b₂Spring + b₄Fall + b₅Rain
