An SPSS output below is the result of a survival data analysis and the question is whether the standard course of a treatment should be extended (maintained) for additional cycles. The question of interest is whether recurrence occurs later in maintained patients than in non-maintained patients. Choose the correct interpretation.
a) Based on the result of survival analysis below, we can conclude that the treatment groups differ significantly in survival at the type I error = 0.10.
b) Based on the result of survival analysis below, we can conclude that the treatment groups do NOT differ significantly in survival at the type I error = 0.05.
c) Since the Exp(B)=.405 does not equal to 1, we can conclude that the treatment groups differ significantly in survival.
d) Since a confidence interval is not provided, we cannot make a conclusion.
