What control limits would give an alpha risk of .03 for this process?
. What alpha risk would control limits of .047 and .003 provide?
. Using control limits of .047 and .003, is the process in control?
. Suppose that the long-term fraction defective of the process is known to be 2 percent. What
are the values of the mean and standard deviation of the sampling distribution?
. Construct a control chart for the process, assuming a fraction defective of 2 percent, using
two-sigma control limits. Is the process in control?
