Assuming the variables: Effectiveness = the response variable measured on a scale from 0 to 100,
Age = the age of a patient (in years) ,
Drug = a binary variable with 1 for the new drug,and 0 for the old drug,the regression model,
Effectiveness = β₀ + β₁Age + β₂Drug + β₃Age × Drug,is considered,and the following Excel results are available: Refer to Exhibit 17.5.What is the predicted effectiveness of the new drug for a 62 years old patient?

• A)21.08
