Corsi et al.(2007) conducted a study of the factors mediating whether injection drug users enter a drug treatment program.One of the factors they explored was marital status.The researchers found that 66 of 135 married (or partnered) drug users entered a treatment program and 67 of 185 single drug users entered a treatment program.They also found that the relative likelihood of entering a treatment program if a user is married is 1.35.This means that:
A) married drug users are 1.37 times more likely to enter a treatment program than are single drug users.
B) single drug users are 1.37 times more likely to enter a treatment program than are married drug users.
C) for every married drug user that enters a treatment program, only 0.37 single drug users enter a treatment program.
D) for every single drug user that enters a treatment program, only 0.37 married drug users enter a treatment program.
