Final answer:
The AMZL Benchmark rate for staffing problem solvers that closely matches with the data provided is option c) 8%, equivalent to 8.1 percent as calculated from Solution 1.19.
Step-by-step explanation:
The student has asked about the AMZL Benchmark rate for staffing problem solvers. Based on Solution 1.19 provided, the benchmark rates given in the options do not directly align with the problem-solver staffing rate. However, the closest figure in the provided solution is option c, which is 67,092/823,356 or 0.081, equating to 8.1 percent. Therefore, the correct answer to the question 'What is the AMZL Benchmark rate for staffing problem solvers?' would be option c) 8%, which closely approximates to 8.1 percent.
