Samples of n = 100 items were selected hourly over a 100-hour period, and the sample proportion of defectives was calculated each hour. The mean of the 100 sample proportions was 0.065. (a) Use the data to find the upper and lower control limits for a p chart. (Round your answers to three decimal places.) UCL = LCL = (b) Construct a p chart for the process.
