Delta Steel Corporation produces? “ball bearing” for robotics industry that have design specification of 5.0in ± 0.1in in diameter.

?Two-hundred ball bearings from the process were sampled. The results showed that the standard deviation of diameter of these ball bearings was 0.02in.

1. The upper specification limit for this ball bearing? = ? inches ?(round your response to three decimal? places).

2. The lower specification limit for this ball bearing? = ? inches ?(round your response to three decimal? places).

3. If the process operates at a mean diameter of 5.0 inches, then the process capability index (Cpk?) ?= ? ?(round your response to three decimal? places).

4. From the above result of Cpk we can state that the process is capable of about (5, 4, or 3) sigma performance.
