5. Green Engineering has developed a prototype conversion unit that allows a motorist to switch from gasoline to electric or vice versa. Its marketing group has compiled the potential NPW distribution at (Table below) for each configuration of conversion unit when marketed independently. Evaluate the expected return and risk for each model configuration, and recommend which one, if any, should be selected. (Note: Green Engineering would like to target one configuration model in offering the conversion kit.)
