Six Sigma (Process Capability)

Need help/assistance on the following six sigma project. I've attached the entire assignment as well as my excel data for the formula and calculations to give you an idea. 90% of this coursework is done. I am having issues with the process capability portion of the assignment(the 8th tab in excel). This is the only part of the assignment I need completed. I answered two of the questions within the Process Capability Assignment correctly but am having issues with getting the right answers/data on the rest. I have submitted this assignment twice (hence you see two different answers) but have been wrong both times.
