Given are six measurements (in ∘ C ) of the melting point of a copper sample: 1084.55 1084.89 1085.02 1084.79 1084.69 1084.86 To access the complete data set, click the link for your preferred software format: Excel Minitab JMP SPSS TI R Mac-TXT PC-TXT CSV CrunchIt! The copper sample is supposed to have melting point of 1084.80 ∘ C. Do the measurements give good evidence that the melting point is not 1084.80 ? The six measurements are an SRS from the population of all results we would get if we kept measuring the melting point of this copper forever. This population has a Normal distribution with mean equal to the true melting point of the copper sample and standard deviation 0.25 . Use this information to carry out a test of significance, following the four‑step process. STATE: Choose which one of the questions gives the best statement of the problem.
