An experiment was performed to compare the fracture toughness of high-purity 18 Ni maraging steel with commercial-purity steel of the same type. For m = 33 specimens, the sample average toughness was x = 64.1 for the high-purity steel, whereas for n = 38 specimens of commercial steel y = 58.6. Because the high-purity steel is more expensive, its use for a certain application can...
