Executive Summary
Statistical analysis was done on the aluminum manufacturing data. Using appropriate tests, some relationships were established. First, sheet metal grade aluminum has the highest production output at sections 1 and 2. However, the standard deviation values are also highest at these two sections. Second, there is evidence that the produced amount of electrical grade aluminum is significantly different (probably higher) than the sheet metal grade aluminum made. Third, there is evidence that the bauxite consumption the bauxite consumption is significantly different (probably higher) than the purchasing policy of 4.2 tons per pot. Lastly, power Continue reading...
