Based on a study, the Lorenz curves for the distribution of incomes for bankers and actuaries are given respectively by the functions 9 f(2)=1/02 + 1/02 and g(z)=0.5425 +0.46 (a) What percent of the total income do the richest 20% of bankers receive? Note: Round off to two decimal places if necessary (b) Compute for the Gini index of f(x) and g(z). What can be implied from the Gini indices of f(z) and g(x)?
