A process molds plastic screw-on caps for containers of motor oil. The strength of properly made caps (the torque that would break the cap when it is screwed tight) has the normal distribution with mean 10 inch-pounds and standard deviation 1.2 inch-pounds. You monitor the molding process by testing a sample of 6 caps every 20 minutes. You measure the breaking strength of the sample caps and keep an xavg chart. Find the center line and control limits for this xavg chart.
Please show all work.
