Tensile-strength tests were carried out on two different gradesof wire rod (Fluidized Bed Patenting of Wire Rods, Wire J.,June 1977: 5661), resulting in the accompanying data.SampleSample Mean SampleGrade Size (kg/mm2) SDAISI 1064AISI 1078a. Does the data provide compelling evidence for concludingthat true average strength for the 1078 grade exceeds thatfor the 1064 grade by more than 10 kg/mm2? Test theappropriate hypotheses using the P-value approach.b. Estimate the difference between true average strengths forthe two grades in a way that provides information aboutprecision and reliability.
