(i) Suppose that the survival distribution of a group of patients follows theexponential distribution with G = 0 (year),λ = 0.65. Plot the survivorshipfunction and find:(a) The mean survival time(b) The median survival time(c) The probability of surviving 1.5 years or more (ii) Suppose that the survival distribution of a group of patients follows theexponential distribution with G = 5 (years) and λ = 0.25. Plot the survivorshipfunction and find:(a) The mean survival time(b) The median survival time(c) The probability of surviving 6 years or more (iii) Consider the following two we bull distributions as survival models:(i) G = 0, 1, γ= 0.5(ii) G = 0, 0.5, γ = 2For each distribution, plot the survivorship function and the hazardfunction and find:(a) The mean(b) The variance(c) The coefficient of variation
