The Elon Company manufactures parts for an air-craft company using three computerized numerical con-trolled (CNC) turning centres. The company wants to decide which machines are capable of producing a specific part with design specifications of 0.2468 cm  ± 0.0382 cm. The machines have the following process parameters: machine 1 (x̅̅ = 0.2531, σ = 0.0102); machine 2 (x̅̅ = 0.2549, σ = 0.0229); machine 3 (x̅̅ = 0.2417, σ = 0.0127). Determine which machines (if any) are capable of producing the products within the design specifications.
