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.What is the regression equation for the winter days?
A) = (b0 + b3) + b1Temperature + b5Rain
B) = (b0 + b2 + b3 + b4) + b1Temperature + b5Rain
C) = b0 + b1Temperature + b5Rain
D)
