Samples of n = 6 items each are taken from a process at regular intervals. A quality characteristic is measured, and x-bar and R values are calculated for each sample. After 50 samples, we have Compute control limits for the x-bar and R control charts. All points on both control charts fall between the control limits computed in part (a). What are the natural tolerance limits of the process? If the specification limits are 41 ± 5.0, what are your...

Control charts are to be kept on the thickness measurements for a process that rolls 10-gage copper sheets. The current specification in the sheets is 0.1360+0.0020 inch. After collecting 25 samples of n 5 measurements at approximately half-hour intervals, the data were used to determine Σ L:3.421 inches and R.-0.044 inches, with i1 to 25. Assume that the quality...

Wakanda Process Manufacturing Samples of n =5 units are taken from a process every hour. The x̄ and R̄ values for a particular quality characteristic are determined. After 25 samples have been collected, we calculate x̄ = 20 and R̄ = 4.56. (a) What are the three- sigma control limit for x̄ and R? (b) Both charts exhibit control. Estimate the process standard deviation. (c) Assume that the process output is normally distributed. If the specifications are 19 ± 5,...

Exposure to arsenic in drinking water is associated with increased prevalence of diabetes. We previously reported an association of diabetes and urinary concentration of dimethylarsinite (DMAS"), a toxic product of arsenic methylation by arsenic (+ 3 oxidation state) methyltransferase (AS3MT). Here we examine associations between AS3MT polymorphism, arsenic metabolism and diabetes. Fasting blood glucose, oral glucose tolerance and self-reported diagnoses were used to identify diabetic individuals. Inorganic...
