You test the effect of the gender and age on survival of patients receiving kidney. You use the proportional hazard model with the indicator variable Z1 = 1 for male patient and Z2 = 1 for adult patient. The resulting parameter estimates are b1 = 0.25, b2 = –0.45. The variance-covariance matrix for b1 and b, is 0.35 0.10 0.10 0.20
