Assumethese values are representative of investors' expectations forfuture performance and that the current T-bill rate is 4%. Calculate the utility levels of each portfolio for an investorwith A = 3. Assume the utility function is U =E(r) ? 0.5 × A?2. (Donot round intermediate calculations. Round your answers to 4decimal places.) WBillsWIndexU(A = 3)0.01.0 0.20.8 0.40.6 0.60.4 1.80.2 0.10.0
