Sam’s Long Life 75-watt light bulbs are designed to have a life of 1,100 hours with tolerances of ±215 hours. The process that makes light bulbs has a mean of 1,000 hours, with a standard deviation of 51 hours. Compute the process capability ratio and the process capability index, and comment on the overall capability of the process. (Round answers to 2 decimal places, e.g. 2.75.) Process capability ratio Entry field with incorrect answer 915 Process capability index Entry field with incorrect answer .82 While Cp = Entry field with incorrect answer indicates the process Entry field with incorrect answer capable, Cpk = Entry field with incorrect answer indicates that Entry field with incorrect answer bulbs will be generated.
