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

Bill Kime's bowling ball factory makes bowling balls of adult size and weight only. The standard deviation in the weight of a bowling ball produced at the factory is known to be 0.39 pounds. Each day for 24 days, the average weight, in pounds, of 9 of the bowling balls produced that day has been assessed as follows Day 1 2 3 4 5 6 Average (lb) 9.9 9.9 10.1 10.1 99 99 Day 7 8 9 10 11 12 Average (lb) Day Average (b) 13 14 15 16 17 18 10.1 10.0 10.0 10.1 10.1 10.0 9.9 10.1 10.1 10.0 10.1 10.1 Day 19 20 21 22 23 24 Average (lb) 99 10.0 10.1 9.9 10.0 10.0 a) Establish a control chart for monitoring the average weights of the bowling balls in which the upper and lower control limits are each two standard deviations from the mean What are the values of the control limits?

Consider the types of poor driving habits that mightoccur at a traffic light. Make a list of the I 0 you consider mostlikely to happen. Add the category of "other" to that list.a) Compose a check sheet [like that in Figure 6.6(a)] to collectthe frequency of occurrence of these habits. Using your checksheet, visit a busy traffic light intersection at four differenttimes of the day, with two of these times being during hightrafficperiods (rush hour, lunch hour). For 15 to 20 minuteseach visit, observe the frequency with which the habits youlisted occurred.b) Construct a Pareto chart showing the relative frequency ofoccurrence of each habit
