New light bulbs are tested for their luminance, with the specifications of 9017.5 lumens. It is known that the luminance is =103.18 on average with a standard deviation of =4.07. Compute the Cp index for the luminance of the light bulbs. (Round to 2 decimal places) Compute the Cpk index for the luminance of the light bulbs. (Round to 2 decimal places) Compute the proportion conforming output for the luminance of the light bulbs. (Round to 4 decimal places) Based on your work above, what is the most accurate description of the manufacturing process for the luminance of light bulbs? The process is capable. The process is not capable because the process standard deviation is too large. The process is not capable because the process mean is seriously off-centered. The process is not capable because both the process mean and standard deviations are problematic
