Homework Assignment 5

Due in Week 6 and worth 30 points.

The data in the table below 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 payment is received (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.

In this assignment you will create control charts for the following data for each country code.

1. Compute the average cycle time for each country code.

2. Compute the moving range for each country code.

3. Compute the confidence interval for each using the average cycle time plus or minus the product of 2.66 times the average moving range for each country code.

4. Turn in the spreadsheet with calculations.

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

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

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

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

Below is the list of country codes and the cycle time for each.
