Exhibit 17.3.Consider the 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.
Refer to Exhibit 17.3.Assuming the same temperature and precipitation condition,what is the difference between the predicted humidity for summer and winter days?
