**Question**

Question;You have learned a lot about your process though the use of the tools and techniques ofSix Sigma. Now you want to be determine whether or not your new processis behaving predictably. So in this deliverable, you need to create an XmR (Individualand Moving Range) chart to answer the question, "Is there any assignable-cause variationin the process?" You are given total deposit cycle time (in hours) by period.InstructionsWe want to make sure you can calculate control limits. You will need toactually construct a control chart by hand.Control Charts in Excel 2003Control Charts in Excel 20071.2.3.4.What is the upper control limit for the range?What is the upper control limit for the individuals?What is the lower control limit for the individuals?What would you do with the process?a. What would you recommend?b. Is the measurement system discriminate?"I'm lost""Do I actually need to do this by hand?""I have no idea about this one"c. Is deposit cycle time in statistical control?"How can I do this without software?"Optional help using Excel 2003Optional help using Excel 2007Data:Data:Period12345678910111213141516171819202122232425262728HoursCycle Time453344305147393469432938454973385040573631464051483742501a.

Justify your answer using ALL of the tests for stability covered in the onlinetextbook and virtual class on SPC.
