An experiment is conducted to compare the maximum load capacity in tons (the maximum weight that can be tolerated without brea

king) for two alloys A and B. It is known that the two standard deviations in load capacity are equal at 7 tons each. The experiment is conducted on 30 specimens of each alloy (A and B) and the results are x overbarAequals65.6, x overbarBequals60.6, and x overbarAminusx overbarBequals5. The manufacturers of alloy A are convinced that this evidence shows conclusively that muAgreater thanmuB and strongly supports the claim that their alloy is superior. Manufacturers of alloy B claim that the experiment could easily have given x overbarAminusx overbarBequals5 even if the two population means are equal. Complete parts (a) and (b) below.
