An office complex leases space to various companies. These leases include energy costs associated with heating during the winter. To anticipate costs in the coming year, the managers developed two random variables X and Y to describe costs for equivalent amounts of heating oil (X) and natural gas (Y) in the coming year. Both X and Y are measured in dollars per BTU of heat produced. The complex uses both fuels for heating, with 4x = Hy and ox=y. Mark the statement below as True or False. If you believe that a statement is false, briefly say why you think it is false. If told that the costs of heating oil and natural gas are uncorrelated, an analyst should then treat the joint distribution as p(x,y)=P(x)p(y). ..... Choose the correct answer below. O A. True OB. False, zero covariance does not imply independence. O C. False, zero covariance implies dependence.
