A quality analyst wants to develop control chart for determining whether four machines, all producing the same product, are under control with regard to a specific quality attribute. Accordingly, she inspected 1000 units of output from each machine, with following results: machine 1 produced 45 defectives, machine 2 had 68 defectives, machine 3 produced 32 defectives, and machine 4 had 39 defects. For the upper as well as lower control limits of .062 and .034, which machine(s), if any, appear(s) to be out of control for proportion of defectives?
