Samples of n=6 items each are taken from a process at regular intervals. A quality characteristic is measured, and xbar and R values are calculated for each sample. After 50 samples, we have i=150xi=2,000andi=150Ri=200 Assume that the quality characteristic is normally distributed. a. Compute control limits for the xbar and R control charts. Round to the hundredths place. CL for R: [1] UCL for R: [2] LCL for R: [3] CL for xbar: [4] UCL for xbar: [5] LCL for xbar: [6] b. If the specification limits are 415.0, what are your conclusions regarding the ability of the process to produce items within these specifications? Complete the sentence by choosing filling in the blanks. Conclusions: The process (is/is not)[7] capable because the Cp estimate equals [8]
