A manager wishes to build a 3-sigma range chart for a process. The sample size is five, the mean of sample means is 45.00, and the average range is 7.90. From Table S6.1, the appropriate value of D3 is 0, and D4 is 2.115. What are the UCL and LCL, respectively, for this range chart? (Do not round intermediate calculations.

At Quick Car Wash, the wash process is advertised to take less than 6 minutes. Consequently, management has set a target average of 320 seconds for the wash process. Suppose the average range for a sample of 10 cars is 10 seconds. Use the accompanying table to establish control limits for sample means and ranges for the car wash process.
West Battery Corp. has recently been receiving complaints from retailers that its 9-volt batteries are not lasting as long as other name brands. James West, head of the TQM program at West's Austin plant, believes there is no problem because his batteries have had an average life of 60 hours, about 10% longer than competitors' models. To raise the lifetime above this level would require a new level of technology not available to West. Nevertheless, he is concerned enough to set up hourly assembly line checks. Previously, after ensuring that the process was running properly, West took samples of 5 9-volt batteries for 25 test to establish the standards for control chart limits. Those 25 tests are shown in the following table: Sample Data Sample Data Hour Hour Sample Taken 1 Sample Taken 1 2 4 5 R 2 3 4 R 1 60 61 60 59 67 61.4 8 14 62 69 51 62 56 60.0 18 55 57 70 56 46 56.8 24 15 67 53 63 69 70 64.4 17 60 45 58 49 57 53.8 15 16 72 58 51 44 64 57.8 28 66 81 61 51 60 63.8 30 17 49 49 58 68…

In quality assurance, we use c-charts for quality characteristics that are discrete and involve yes/no or good/bad decisions. True or False. Why?
The measurement of 85 automotive cables gave an arithmetic mean of the inner diameters of 3.51 mm and a standard deviation of 0.02 mm.The value required by the manufacturer is 3.5 upper/lower tolerance +0.04/ -0.12It is requested : a. Calculate the capability coefficients Cp, Cpk and state whether or not the machine is capable of producing compliant parts, i.e. whether or not the data dispersion is well centred. If applicable, calculate the adjustment coefficient Cr.b. If scrap is obtained, state whether it is recoverable or non-recoverable and calculate the percentage of scrap.c. Plot the limits of the tolerance field and the distribution of the measured data (using mean and standard deviation).
