Chandler Enterprises produces Pentium chips. Five types of defects (labeled 1-5) have been known to occur. Chips are manufactured by two operators (A and B). Four machines (1-4) are used to manufacture chips. The file P2_76.XLS contains data for a sample of defective chips including the type of defect, operator, machine, and day of the week. Use the data in this file to chart a course of action that would lead, as quickly as possible, to improved product quality. You should use the Pivot Table Wizard to “stratify” the defects with respect to type of defect, day of the week, machine used, and operator working. You might even want to break the data down by machine and operator (or in some other way). Assume that each operator and machine made an equal number of products.
