ll Consider the capability of a process that puts pressurized grease in an aerosol can. The design specification calls for an average of 50 pounds per square inch (psi) of pressure in each can with an upper tolerance limit of 56psi and a lower tolerance limit of 46psi. A sample is taken from production, and it is found that the cans average 51psi with a standard deviation of 2psi. Find the following unknowns. 1. Capability Index (Cpk) 2. Is the process capable at the 30 level? 3. What is the probability of producing a defect? Hind: use the standard normal table as seen below.
