Question

10 pts Question 9 9.[10 points] Air pressure must be in a tight range for the proper performance of aerosol air fresheners. Engineering specifications.call for 50 PSI of pressure with an upper tolerance of 58 PSl and a lower tolerance of 42 PSI. A sample from the previous week's production provides point estimates for average at 52 PSI and standard deviation at 2.5 PSI. a) Calculate the Process Capability Indices: Cp and Cpk. b) Does the process have the potential to meet the specifications? How are you able to determine? c) Is the process capable based on observed process performance? How are you able to determine? Upload Choose a File
