Question
![A clinical trial is conducted to evaluate the
efficacy of a new medication to relieve the pain in patients undergoing
total knee replacement surgery. In the trial, patients are randomly
assigned to receive either the new medication or the standard medication.
The data presented are analyzed using multiple linear regression analysis
and the models are shown here. In the models, the data are coded as
1=new medication and 0-standard medication, and age 65 and older
coded as 1-yes, 0=no.
ŷ-53.85-23.54 medication.
ŷ 45.51-20.21 medication+14.29 Age65+ +0.78 Medication x Age65+
(1) Write out the regression equations for two groups separately:: Age65+,
and age is less than 65.
(2) Does it appear that there is effect modification by age? Why?](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fbd0db42a-6bc6-4fb8-919d-acf0eaef6eca%2F05598ed1-d754-4078-b095-15e20e279ef7%2F169vtvp_processed.jpeg&w=3840&q=75)
