ses An experiment is conducted to compare the maximum load capacity in tons (the maximum weight that can be tolerated without breaking) for two alloys A and B. It is known that the two standard deviations in load capacity are equal at 6 tons each. The experiment is conducted on 40 specimens of each alloy (A and B) and the results Home are XA = 63.1, XB = 59.1, and XA - XB = 4. The manufacturers of alloy A are convinced that this evidence shows conclusively that HA > HB and strongly supports the claim that their alloy is superior. Manufacturers of alloy B claim that the experiment could easily have given XA - XB = 4 even if the two population means are equal.
