# Assignment

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.

Instructions
For each country code you will answer the following questions:
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?
Use the excel template provided by the instructor and use this along with the instructional video to solve for each response per country code.
Once done, you will use the responses in the template which you generate to respond to the questions asked for each country code.
Always remember to reach out to the instructor and attend all available live sessions as needed.
Once done with this assignment you should have a strong understanding of how we obtain averages, upper and lower confidence limits,
and equivalent measures of the average moving range to create the control charts. These will help you visualize where common cause variation exists or special cause variation is present.
