THIS FILE contains the production data of 15 firms operating in an industry. Each firm used three inputs, namely capital (K), labor (L) and other material (M), to produce output (q). Assuming all use CRS technologies, perform an efficiency analysis using the input-oriented' DEA method. What are correct? Select one or more: Select one or more: The average efficiency index of all firms (round to the nearest 3-digit) is 0.407. The least efficient is firm No.14. I 3 firms have been used as the benchmark (the most efficient) firms to measure the efficiency of all others. The highest-weight benchmark in evaluating the efficiency of firm No.11 is firm No.1.
