The life table function for the members of a stationary animal population is given by Q(x)=1- 0≤x≤k, where x is measured in years. (a) Show that the mean lifetime for members of this population is 2k/3. (b) Find the mean age of the members of the population at any time. (c) (i) What proportion of members of the population live for longer than k/2 years? (ii) At any time, what proportion of members of the population are more than k/2 years old?
