Q2

The data in below table lists country code and the order to remittance (OTR) time for hardware / software installations for the last 76 installations (from first to last). OTR is the time it takes from an order being placed until the system is installed and we receive payment (remittance). Because this company does business internationally, it also notes the country of installation using a country code. This code is listed in the first column.

Use the date in table above and answer the following questions in the space provided below:

1.       Does the OTR time appear to be stable?  Why or why not?

2.       If you were to use a control chart to evaluate stability, which chart would you use?  Why?

3.       What can you learn about the distribution of the installation process? 

4.       Does it appear that the country has an impact on installation time? Why or why not?

Q3

Q4

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.

Use the date in table above and answer the following questions in the space provided below:

1.       What was the average effect of the process change? Did the process average increase or decrease and by how much?

2.       Analyze the data using the regression model y = b0 + b1x, where y = time to approve and mail a claim (weekly average), x = 0 for the old process, and x = 1 for the new process.

3.       How does this model measure the effect of the process change?

4.       How much did the process performance change on the average? (Hint: Compare the values of b1 and the average of new process performance minus the average of the performance of the old process.)
