a) They reported an estimated effect on the hazard rate of e=2.13 for the coefficient of the dummy variable for being black. Explain how to interpret.

b) The gender effect was not significant, but they reported an estimated multiplicative effect on the hazard of 1.06 for the dummy variable for being feinale Interpret
