An appliance repair company is considering relocating the center that houses its service vehicles. An internal auditor wants to determine the potential reduction in average miles driven by the service vehicles if the center is relocated. Which of the following statistical sampling methods would be most appropriate for this test?
For an internal auditor to determine the potential reduction in average miles driven by service vehicles, the Mean-per-unit sampling method is most appropriate. This sampling technique estimates the mean (average) value of a variable by examining individual units (service vehicles in this case) and calculating the mean miles driven. It is suitable for estimating averages and provides accuracy when dealing with continuous variables like distance or mileage.
Explain
The internal auditor wants to determine the new AVERAGE MILES (for all vehicles in the sample). By the way, this type of variables is estimated through Mean-per-unit sampling.
