###### An experiment was performed t0 compare the fracture toughness of high purity 18 Ni maraging steel with commercial-purity stell of the same type: For m = 32 specimens; the sampe average toughness was X == 65.6 for the high-purity steel, whereas for n = 38 specimans of commerical steel the average toughness was Y = 59.8 Because high-purity steel is more expensive; its use for certain application can be justifed if its fracture thoughness exceeds that of commercial-purity steel by more than 5.Assum
