Set up limits for the R–bar chart, given R–bar = 0.82 and n = 6.
Answer to relevant QuestionsSet up limits for the R–bar chart, given R–bar = 12 and n = 3. Find the Cp and Cpk indexes for a process with μ = 0.426, σ = 0.001, LSL = 0.423, USL = 0.432. How would you rate the capability of this process? Explain. Bob said, "We use the normal distribution to set the control limits for the x chart because samples from processes follow a normal distribution." Is Bob right? Explain. 17.50 Refer to the paint thickness problem 17.49. Assume μ = σ 1.00 and 5 0.07. Use the following 35 individual observations on paint thickness to answer the questions posed. (a) Prepare a histogram and/or normal ...Each gum drop in two bags of Sathers Gum Drops was weighed (to the nearest .001 g) on a sensitive Mettler PE 360 Delta Range scale. After removing one outlier (to improve normality), there were 84 gum drops in the sample, ...
