Homework Assignment 7  Due in Week 8 and worth 30 points The experiment data in below table was to evaluate the effects of three variables on invoice errors for a company. Invoice errors had been a major contributor to lengthening the time that customers took to pay their invoices and increasing the accounts receivables for a major chemical company. It was conjectured that the errors might be due to the size of the customer (larger customers have more complex orders), the customer location (foreign orders are more complicated), and the type of product. A subset of the data is summarized in the following Table.  Table: Invoice Experiment Error Customer Size Customer Location Product Type Number of Errors - - - 15 + - - 18 - + - 6 + + - 2 - - = 19 + - = 23 - + = 16 + + = 21 Customer Size: Small (-), Large (+) Customer Location: Foreign (-), Domestic (+) Product Type: Commodity (-), Specialty (=) Reference: Moen, Nolan, and Provost (R.

Homework Assignment 6 Due in Week 7 and worth 30 points The data in the table below is from a study conducted by an insurance company to determine the effect of changing the process by which insurance claims are approved. The goal was to improve policyholder satisfaction by speeding up the process and eliminating some non-value-added approval steps in the process. The response measured was the average time required to approve and mail all claims initiated in a week. The new procedure was tested for 12 weeks, and the results were compared to the process performance for the 12 weeks prior to instituting the change. Table: Insurance Claim Approval Times (days)     Old Process  New Process Week Elapsed Time Week Elapsed Time 1 31.7 13 24 2 27 14 25.8 3 33.8 15 31 4 30 16 23.5 5 32.5 17 28.5 6 33.5 18 25.6 7 38.2 19 28.7 8 37.5 20 27.4 9 29 21 28.5 10 31.3 22 25.2 11 38.6 23 24.5 12 39.3 24 23.5 Use the date in table ab...
