Two hundred clinics are considered using a DEA model. The efficiency score for Unit 1 is 0.90 and the results suggest that the reference set for this unit involves only Unit 2 and Unit 3. Units 1, 2, and 3 have identical outputs but different levels of 2 inputs. Which of the following statements are NOT true about efforts to get Unit 1 to be 100% efficient? Group of answer choices If Unit 1 changes it input levels to match Unit 2 it will be 100% efficient If Unit 1 changes it input levels to match Unit 3 it will be 100% efficient A composite unit which has input levels that are a linear combination of the levels for Units 2 and 3 will be 100% efficient Unit 1 can only be 100% efficient if it matches either Unit 2 or Unit 3 exactly None of these statements are true
