An аnаlyst used dаta frоm a pandas DataFrame tо fit a multiple linear regressiоn model that predicts annual_spend using both visits_per_month and is_premium_member. The variable is_premium_member takes on the value of 1 if the customer is a premium member and a value of 0 if the customer is not a premium member. The fitted model is given by the equation: Model predicting annual_spend: annual_spend = 120 + 15*(visits_per_month) + 40*(is_premium_member) Interpret the coefficient for is_premium_member (the one with a value of 40).
