MCMC approximations to the posterior distributions of hazard rate and reliability functions at \(t_{13}=23.13\). It is evident here that the posterior median of hazard rate is 0.078 with 95 % credible interval (0.06, 0.11) represented by the dotted lines. The reliability function has a 95 % credible region (0.22, 0.42) shown with the dotted lines and has median at 0.32. Moreover, the density of hazard function is right-skewed while the reliability distribution assumes a left-skewed shape
