Your supervisor, Lisa Lehmann, has asked that you report on the output of a machine on the factory floor. This machine is supposed to be producing optical lenses with a mean weight of 50 grams and a range of 3.5 grams. The following table contains the data for a sample size of n=6 taken during the past 3 hours: Sample 1 2 3 4 5 6 7 8 9 10 x 55 47 49 50 52 57 55 48 51 56 R 3 1 5 3 2 6 3 2 2 3 Part 2 Set the control limits for this process for the x-chart when the machine is working properly. UCL-x = _______? grams (round to two decimal places) LCL-x = ________? grams (round to two decimal places) B) Set the control limits for this process for the R-chart. UCLr = ________? grams (round to two decimal places) LCLr = _________? grams (round to two decimal places)
