An open label study where participants are aware of the trea

An open label study (where participants are aware of the treatment they are taking) is conducted to assess the time to pain relief following treatment in patients with arthritis. The following linear regression equations are estimated relating time to pain relief measured in minutes (dependent variable) to participants

Solution

A. Using the second equation:

time to pain relief=11.8+19.3(male)=31.1

B. Using the first equation:

time to pain relief=-24.2+.9(age)=20.8
