The time to relapse, in months, for patients on two treatments for lung cancer is compared using the following log normal regression model: $Y = ln(X) = 2 + 0.5Z + 2W$, where $W$ has a standard normal distribution and $Z = 1$ if treatment A and 0 if treatment B. (a) Compare the survival probabilities of the two treatments at 1, 2, and 5 years. (b) Repeat the calculations if $W$ has a standard logistic distribution. Compare your results with part (a).
