Established in 2002, t-shirts.com has rapidly become the place to find, order, and save on T-shirts. One huge selling factor is that the company manufactures its own T-shirts. How ever, the quality manager for the production plant, Kasey Hamish, has noticed an unac ceptable number of defective T-shirts being produced. You have been hired to assist Kasey in understanding where the problems are concentrated. He suggests using a PivotTable to perform an analysis and has provided you with a data file, T3_TshirtProduction_Data.x/s. The following is a brief definition of the information within the data file: A. Batch: A unique number that identifies each batch or group of products produced. B. Product: A unique number that identifies each product. C. Machine: A unique number that identifies each machine on which products are produced. D. Employee: A unique number that identifies each employee producing products. E. Batch Size: The number of products produced in a given batch. F.
