Twenty-One samples of 100 items each were inspected when a process was considered to be operating satisfactorily. In the 21samples, a total of 140 items were found to be defective. a. What is an estimate of the proportion defective when the process is in control? Round your answer to four decimal places.   b. What is the standard error of the proportion if samples of size 100 will be used for statistical process control? Round your answer to four decimal places.   c. Compute the upper and lower control limits for the control chart. Round your answers to four decimal places. If answer of LCL is negative, enter “0”
