Twelve samples, each containing five parts, were taken from a process that produces steel rods at Emmanual Kodzi's factory. The length of each rod in the samples was determined. The results were tabulated and sample means and ranges were computed. The results were: Sample Sample Mean (in.) Range (in.) Sample Sample Mean (in.)

Question 1: A company making tires for bikes is concerned about the exact width of its cyclocross tires. The company has a lower specification limit of 22.8 mm and an upper specification limit of 23.2 mm. The standard deviation is 0.15 mm and the mean is 23 mm. What is the process capability index (Cpk) for the process? Question 2: Consider again that the company making tires for bikes is concerned about the exact width of its cyclocross tires. The company has a lower specification limit of 22.8 mm and an upper specification limit of 23.2 mm. The standard deviation is 0.15 mm and the mean is 23 mm. What is the probability that a tire will either be too wide or too narrow?

Self-Study Problem 17-2 (Algo) Taguchi Quality Loss Function (QLF) [LO 17-4] Marlon Audio Company manufactures video tapes. The desired speed of its model SF2000 is 6 inches per second. Any deviation from this value distorts pitch and tempo, resulting in poor sound quality. The company sets the quality specification to 6 ± 0.29 inch per second because an average customer is likely to complain and return the tape if the speed is off by more than 0.29 inch per second. The cost per return is $40. The repair cost before the tape is shipped, however, is only $2 per tape. Required: 1. Compute L(x) if x is 6.12 inches per second. 2. Estimate the tolerance for the firm to minimize its quality-related cost (loss). (Round your answers to 4 decimal places.) 1. L(x) 2. Tolerance inch
