.0272 and .0128 .029 and .013 .0332 and .0068 .0287 and .0113 .0303 and .0097 A Quality Analyst wants to construct a control chart for determining whether four machines, all producing the same product, are under control with regard to a particular quality attribute. Accordingly, she inspected 1,000 units of output from each machine in random samples, with the following results: What is the sample proportion of defectives for machine #1? What is the estimate of the process proportion of defectives for whenever it is under control?
