it A plant tests for radiation in the titanium parts receives from its Suppliers. Sometimes a test yields inconclusive results and it must be repeated Use the following data on retests for each of the 13 Samples. N = 197 Sample # # of Retests 1 2 3 4 5 6 7 8 9 10 11 12 13 2 202 201 8 2 A.) Determine the upper and lower control limits for the fraction of retests using two sigma limits (Round to 4-decimal places) UCL = LCL= B.) Is the process in control?
