An open-label study (where participants are aware of the treatment they are taking) is run 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 (dependant variable) to participant's age (in years), gender (coded 1 for males and 0 for females), and severity of disease (a score ranging from 0 to 100, with higher scores indicative of more severe arthritis):
Time to Pain Relief= -24.2 + 0.9 Age
Time to Pain Relief= 11.8 + 19.3 (Male Gender)
Time to Pain Relief= 3.2 + 0.4 Severity
Time to Pain Relief= -19.8 + 0.5 Age + 10.9 (Male Gender) + 0.2 Severity
A. What is the expected time to pain relief for a male following treatment?
