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

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 b = 0.25, b2 = -0.45. The variance-covariance matrix for b1 and b, is
0.35 0.10
0.10 0.20
Which (approximately) of the following 95% for the hazard ratio of a male child patient compared to
female adult patient?
