Question:
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.
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 =
