4. Problem 8.29 The number of imperfections in bond paper produced by a paper mill is
observed over a period of several days. Table 8-28 shows the area inspected and the
number of imperfections for 25 samples. Construct a control chart for the number of
imperfections per square meter. Revise the limits, if necessary, assuming special causes for
the out-of-control points.
